      Digitization and Intelligence Mass Flowmeter

      1.Mass flowmeter is a flow measurement instrument using the advanced Coriolis principle in the world.

      2.Mass flowmeter can directly measure the mass flow rate, volume flow rate, density and temperature parameters of the fluid.

      3.Mass flowmeter can display instantaneous and cumulative mass flow, volume flow, density, temperature parameters through the LCD screen, can output pulse signal and current signal, with 485 communication function.

    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.

    Product component:

    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.

    Installation of instrument:

    Horizontal pipe：Main face down，Liquid Measure

    Horizontal pipe：Main face up,Measure grout,gas or liquid

    Vertical pipeline：Flag mounting，Measuring liquid or solid containing slurry,The liquid flows from below
