What is the difference between electromagnetic flowmeter, flow transmitter and flow sensor?.
The split is generally a flow sensor and a flowmeter body into one flow transmitter as a separate switch body, installed in the field. The flow velocity sensor, which is sensed by the flow sensor, is converted into a weak electrical signal, which must be processed by a flow transmitter before it can be converted to a standard signal (4~20mA). At the same time, the transmitter also has the flow accumulation, alarm output, intelligent communications and other extensions. Transmitter is usually composed of signal acquisition unit, signal processing unit and power supply unit.
Electromagnetic flowmeter is a general term, it usually has two types of integral and split type. Integrated flow sensors and flow transmitters are all integrated into the flowmeter body, which is the most common.
The advantages of the split is, for some high temperature, excessive vibration place, can reduce the temperature and vibration effects on the transmitter, prolong the service life, installation position for some flowmeter is high, the split can also lower installation, convenient maintenance.Of course, the part of the flow transmitter and flow sensor cable between the length of certain requirements, matching should be explained.
