Embodiment 1

[0031] Such as figure 1 A kind of differential pressure flowmeter water treatment method shown, this method comprises the following steps:

[0032] Step 1: Install the two-way solenoid valve, and connect the two-way solenoid valve to the exhaust channel and the pressure-taking channel respectively;

[0033] Step 2: Install the differential pressure flowmeter in the compressed air pipeline for measurement;

[0034] Step 3: Analyze the differential pressure value data detected by the differential pressure flowmeter. The specific steps for analyzing the differential pressure value data are as follows: When the pressure in the pipeline is greater than 0.1Mpa, if there is a negative differential pressure value, it is judged as data Abnormal, otherwise it is judged that the data is normal;

[0035] If the data is normal, go to step five; if the data is abnormal, it is judged as water interference and go to step four;

[0036] Step 4: Control the two-way solenoid valve to be clean...

[0039] Such as figure 1 A kind of differential pressure flowmeter water treatment method shown, this method comprises the following steps:

[0040] Step 1: Install the two-way solenoid valve, and connect the two-way solenoid valve to the exhaust channel and the pressure-taking channel respectively;

[0041] Step 2: Install the differential pressure flowmeter in the compressed air pipeline for measurement;

[0042] Step 3: Analyze the differential pressure value data detected by the differential pressure flowmeter. The specific steps for analyzing the differential pressure value data are as follows: set the differential pressure change threshold and adjust according to the differential pressure value of the pipeline and the differential pressure sensing diaphragm. Response characteristics Calculate the maximum differential pressure change value in the pipeline. If the differential pressure change value exceeds the change threshold, it is judged as abnormal data, otherwise it i...

Embodiment 3

[0047] Such as figure 1 A kind of differential pressure flowmeter water treatment method shown, this method comprises the following steps:

[0048] Step 1: Install the two-way solenoid valve, and connect the two-way solenoid valve to the exhaust channel and the pressure-taking channel respectively;

[0049] Step 2: Install the differential pressure flowmeter in the compressed air pipeline for measurement;

[0050] Step 3: Analyze the differential pressure value data detected by the differential pressure flowmeter. The specific steps for analyzing the differential pressure value data are as follows: Set the fluctuation period threshold value of the differential pressure value. If the fluctuation period of the differential pressure value exceeds the fluctuation period The threshold is judged as abnormal data, otherwise it is judged as normal data;

[0051] If the data is normal, go to step five; if the data is abnormal, it is judged as water interference and go to step four; ...

Abstract

The invention discloses a method for treating water for differential pressure flow meters. The method includes steps of firstly, mounting two-way electromagnetic valves and connecting the two-way electromagnetic valves with exhaust passages and pressure tapping passages; secondly, mounting the differential pressure flow meters in compressed air pipelines and carrying out measurement; thirdly, analyzing differential pressure value data detected by the differential pressure flow meters, carrying out a fifth step if the data are normal, or determining that water interference is available if the data are abnormal and carrying out a fourth step; fourthly, carrying out cleaning by the aid of the two-way electromagnetic valves under the control and carrying out the fifth step after cleaning is completely carried out; fifthly, utilizing the acquired differential pressure value data as valid data and allowing the valid data to participate in flow calculation. The method has the advantages thatthe problem of inaccurate flow measurement due to water vapor in measurement media can be effectively solved by the aid of the method, abnormal fluctuation of measurement data can be prevented, the pipeline internal flow measurement accuracy can be guaranteed, and the method can be applied to optional compressed air measurement places with water interference, is wide in application range and has excellent utilization and popularization values.

Description

technical field [0001] The invention belongs to the field of flow measurement, in particular to a water treatment method for a differential pressure flowmeter. Background technique [0002] With the development of science and technology, the application of automated production is becoming more and more extensive. Compressed air, as the main source of power for automated production, is gradually expanding its application in the industry. Compressed air manufacturing equipment, air compressors account for a large proportion of energy consumption in the factory, so the flow monitoring of compressed air will become more and more important, but most of the compressed air uses water vapor. During the use of ordinary pitot tube differential pressure flowmeter, the water vapor will condense into water droplets on the inner wall of the pressure tapping tube. As the condensed water increases, a water film will be formed in the pressure tapping tube. Neither the static pressure nor th...
