Description

Technical Field

[0001] The invention relates to the technical field of flow meters, in particular to a flow meter with a temperature measurement alarm function. Background Art

[0002] Electromagnetic flowmeter is a new type of flowmeter, which uses the principle of electromagnetic induction to measure the velocity flow rate, cumulative flow rate, etc. of the fluid. There is no flow resistance and no moving parts in the flowmeter pipeline. Its measuring cylinder is lined with various anti-corrosion materials, which has excellent corrosion resistance and no flow resistance. It is not only suitable for measuring general conductive liquids, but also suitable for measuring strong corrosive liquids such as strong acids, strong alkalis, and salts. Therefore, it has a wide range of uses. The electromagnetic flowmeter with temperature measurement is based on the general electromagnetic flowmeter. A temperature sensor is added to the sensor cylinder to detect the temperature of the liquid flowing through the electromagnetic flowmeter. The measured temperature parameter can be displayed on the display screen of the electromagnetic flowmeter head, or by adding a 4-20mA signal of an analog output temperature signal, or by outputting the flow signal and temperature signal simultaneously through the relative HART, MODBUS and other communication protocols, to achieve multi-parameter measurement of the electromagnetic flowmeter.

[0015] Compared with the prior art, the present invention provides a flow meter with temperature measurement alarm function, which has the following beneficial effects:

[0016] 1. The flow meter with temperature measurement alarm function is provided with an alarm light. The information transmitted to the first signal contact electrode will pass through the line in the connecting and fixing ring to reach the first connecting line and finally reach the processing module for processing. When the temperature sensor in the circulation pipe on one side of the lining is abnormal, the processing module will control the alarm light on the connecting and fixing ring on the corresponding side of the temperature sensor to flash for warning, and the processing module will control the alarm to emit an alarm prompt sound. When the liquid temperature in the circulation pipes on both sides of the lining is abnormal, the processing module will control the alarm lights on the connecting and fixing rings on the circulation pipes on both sides to flash for warning, and the processing module will control the alarm to emit an alarm prompt sound, so as to facilitate the distinction between sensor false alarms and abnormal actual liquid temperature, and facilitate the operator to carry out classified emergency treatment.

[0017] 2. The flow meter with temperature measurement and alarm function is provided with a connection component, the temperature sensor is installed on the second signal contact electrode, and then the temperature sensor is aligned with the bottom middle position of the anti-corrosion grounding pipe, the connection rotating groove is aligned with the anti-corrosion grounding pipe and the first knob is rotated. When the first knob is rotated, the fixed shaft will be driven to rotate. When the fixed shaft rotates, the first thread is engaged with the first thread groove, and the fixed shaft will move upward in the anti-corrosion grounding pipe. When the first knob is rotated to contact the bottom of the anti-corrosion grounding pipe, the temperature sensor is completely fixed in the temperature measuring groove. When the fixed shaft rotates and moves upward in the anti-corrosion grounding pipe, the sensor mounting block on the upper part of the fixed shaft is fixedly installed with the second signal contact electrode on one side close to the first signal contact electrode, so the second signal contact electrode will move in the moving groove on the anti-corrosion grounding pipe, and the first limit block at the bottom of the sensor mounting block will rotate in the connection rotating groove on the upper part of the fixed shaft. When the first knob is rotated to contact the bottom of the anti-corrosion grounding pipe, the second signal contact electrode can be brought into contact with the first signal contact electrode, which is convenient for the installation of the temperature measuring component.

[0018] 3. The flow meter with temperature measurement alarm function is provided with a temperature measuring component. When the first knob is rotated to contact the bottom of the anti-corrosion grounding pipe, the second signal contact electrode can be brought into contact with the first signal contact electrode. Thus, the temperature information detected by the temperature sensor in the flow pipe can be transmitted to the first signal contact electrode through the second signal contact electrode on the sensor mounting block, which is convenient for temperature detection of the circulating liquid.

[0019] 4. The flow meter with temperature measurement and alarm function is arranged through the flow meter assembly. When the charged liquid passes through the lining, the excitation coils above and below the lining will generate a magnetic field, and the electrodes on the front and rear sides of the lining will measure the voltage between the electrodes and transmit the information to the processing module through the first connecting pipe. The processing module converts the voltage information between the electrodes on both sides of the lining into flow information and displays it on the display screen, thereby measuring the liquid flow through the lining and the circulation pipe.

[0020] 5. The flow meter with temperature measurement and alarm function is provided with an anti-corrosion grounding pipe. When it is necessary to detect whether the temperature sensor is working normally, the temperature in the circulation pipe is changed, and the alarm light and the alarm are observed to see whether an abnormal alarm is given. This is used to infer whether the temperature sensor is working normally. If the alarm light and the alarm do not sound due to an abnormal temperature sensor, the temperature sensor can be removed and replaced. Specifically, the first knob is turned. When the first knob is turned, the fixed shaft is driven to rotate. When the fixed shaft rotates, the first thread engages with the first thread groove. The fixed shaft moves downward in the anti-corrosion grounding pipe. The fixed shaft is rotated and taken out from under the anti-corrosion grounding pipe. The temperature sensor above the sensor mounting block is taken out for replacement. The temperature measuring assembly can be reinstalled in the connecting assembly to facilitate replacement when the temperature sensor is abnormal. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] When in use, first install the temperature measuring component 400 in the connecting component 300, specifically, install the temperature sensor 408 on the second signal contact electrode 407, then align the temperature sensor 408 with the bottom middle position of the anti-corrosion grounding pipe 301, align the connecting rotating groove 404 with the anti-corrosion grounding pipe 301 and turn the first knob 401. When the first knob 401 is rotated, the fixed shaft 402 is driven to rotate. When the fixed shaft 402 rotates, the first thread 403 engages with the first thread groove 304, and the fixed shaft 402 moves upward in the anti-corrosion grounding pipe 301. When the first knob 401 is rotated to contact the bottom of the anti-corrosion grounding pipe 301, the temperature sensor 408 is completely fixed in the temperature measuring groove 305. When the fixed shaft 402 rotates in the anti-corrosion grounding pipe 30 1, the sensor mounting block 405 on the upper part of the fixed shaft 402 is fixedly mounted with the second signal contact electrode 407 on one side close to the first signal contact electrode 206, so the second signal contact electrode 407 will move in the moving groove 303 on the anti-corrosion grounding pipe 301, and the first limit block 406 at the bottom of the sensor mounting block 405 will rotate in the connecting rotation groove 404 on the upper part of the fixed shaft 402.

[0042] The information transmitted to the first signal contact electrode 206 will pass through the line in the connecting and fixing ring 201 to reach the first connecting line 203 and finally reach the processing module 109 for processing. When the temperature sensor 408 in the circulation tube 105 on one side of the lining 108 is abnormal, the processing module 109 will control the alarm light 202 on the connecting and fixing ring 201 on the corresponding side of the temperature sensor 408 to flash for warning, and the processing module 109 will control the alarm 204 to emit an alarm prompt sound.

[0043] When charged liquid passes through the liner 108, the excitation coils 104 above and below the liner 108 will generate a magnetic field, and the electrodes 103 on the front and rear sides of the liner 108 will measure the voltage between the electrodes 103 and transmit the information to the processing module 109 through the first connecting pipe 107.

[0044] When it is necessary to detect whether the temperature sensor 408 is working normally, change the temperature in the circulation tube 105, and observe whether the alarm light 202 and the alarm 204 issue an abnormal alarm, so as to infer whether the temperature sensor 408 is working normally. If the temperature sensor 408 is abnormal and the alarm light 202 and the alarm 204 do not alarm, the temperature sensor 408 can be removed and replaced. Specifically, the first knob 401 is rotated. When the first knob 401 is rotated, the fixed shaft 402 is driven to rotate. When the fixed shaft 402 is rotated, the first thread 403 engages with the first thread groove 304, and the fixed shaft 402 moves downward in the anti-corrosion grounding pipe 301. The fixed shaft 402 is rotated and removed from the bottom of the anti-corrosion grounding pipe 301, and the temperature sensor 408 above the sensor mounting block 405 is removed for replacement, and the temperature measuring component 400 is reinstalled in the connecting component 300.
