The JDMF series Mass flowmeter has the advantages of simple structure, low requirements for field pipeline installation and medium cleanliness, and high precision, wide range ratio, simple and convenient maintenance. Can be widely used in petroleum, chemical industry, metallurgy, shipping, power, food, medicine, environmental protection and energy industry process testing and trade measurement occasions, is an advanced flow metering instrument.
This product is composed of two parts: detection element (primary instrument) and converter (secondary instrument).
The detection element (primary instrument) is equipped with an exciter, a displacement sensor and a temperature sensor.
The converter (secondary instrument) is the display part of the instrument and also the electrical part of the instrument. Its basic function is: receive and process the electrical signal of the detection component, can display, output, storage and remote transmission, modify the flow meter parameters.
