Problems solved by technology
[0004] However, for longer range liquid level measurement, segmented liquid level transmitters are often used in general; Transmitter, each liquid level transmitter inputs a current signal of 4-20mA respectively, and the control display system connected to it will receive three measurement results. Since the three measurement results are relatively independent, the entire liquid level cannot be continuously monitored and displayed. The signal of the meter is very inconvenient to use and the measurement accuracy is relatively poor

The embodiment of the invention provides a magnetic liquid level transmitter. The magnetic liquid level transmitter comprises a magnetic-levitation liquid level meter and liquid level transmitters. Sensors of the liquid level transmitters are fastened outside a main body pipe of the magnetic-levitation liquid level meter. The liquid level transmitters comprise A-type liquid level transmitters andB-type liquid level transmitters. The A-type liquid level transmitters are formed by electric connections among the sensors and connectors. The B-type liquid level transmitters are formed by electricconnections among the sensors and convertors. The multiple A-type liquid level transmitters and one B-type liquid level transmitters are orderly arrayed along the axial direction of the liquid level meter. An outgoing wire end of a former A-type liquid level transmitter is electrically connected with an ingoing wire end of a next A-type liquid level transmitter adjacent to the former A-type liquidlevel transmitter. An ingoing wire end of each B-type liquid level transmitter is electrically connected with an outgoing wire end of a former A-type liquid level transmitter adjacent to the above B-type liquid level transmitter. An outgoing wire end of each B-type liquid level transmitter is electrically connected with a control system so that liquid level signals can be continuously displayed.The magnetic liquid level transmitter has the effect of continuously and accurately monitoring and displaying a signal of the overall liquid level meter.
Description
technical field [0001] The invention relates to the field of liquid level measuring instruments, in particular to a magnetic liquid level transmitter. Background technique [0002] In petrochemical and other fields, liquid level gauges are often used to measure the liquid level of liquid media in containers. The types of liquid level gauges include tuning fork vibration type, magnetic levitation type, pressure type, ultrasonic wave, sonar wave, magnetic flap and radar, etc. Among them, the magnetic float level gauge is mainly used in liquid level measurement in the fields of petroleum processing, food processing, chemical industry, water treatment, pharmaceutical, electric power, papermaking, metallurgy, shipbuilding and boilers. The magnetic float level gauge has a top-mounted float level gauge and a side-mounted float level gauge. It can be equipped with a remote liquid level transmitter to realize the digital / analog display of the liquid level signal. [0003] Liquid le...
