The smaller the range ratio, the greater the pressure drop.

The mass flowmeter measures the mass and density of the fluid medium. The range ratio of the instrument will affect its own measuring accuracy, but there is no suggestion that it will cause a pressure drop. Mass flowmeter is a mass measuring instrument made according to Coriolis force effect, so the detection of mass flowmeter is not affected by temperature, pressure, flow rate, density, viscosity, etc.

Characteristics of mass flowmeter

The mass flowmeter has the advantages of high detection accuracy, wide range, high reliability and small maintenance. When measuring the mass flow rate of the fluid medium, the density of the fluid medium can also be measured. Its output signal is 4-20maDC analog signal, at the same time can output frequency signal, can be better compatible with the computer, the formation of a complete safety system. Due to the above characteristics of mass flowmeter, although the price is expensive, but in the industrial automated production process is widely popular, so it has been rapidly popularized and applied.

Composition of mass flowmeter

Mass flowmeter is composed of sensor, transmitter and display instrument. The shape of the measuring tube for the detection element sensor varies from manufacturer to manufacturer.

Working process of mass flowmeter

Although the manufacturers are different, the principles of the sensor industry are the same. The fluid medium vibrates the measuring tube through the exciting coil, and the fluid medium generates Ge force in the vibration tube. Because the Ge force generated by the fluid medium at the inlet and outlet of the measuring tube is equal in magnitude and opposite in direction, the vibrating tube will be distorted. The fluid medium, through the electromagnetic detector or photodetector, converts the distortion generated by the measuring tube into an electrical signal and outputs it to the transmitter for further processing. The transmitter converts the sent electrical signal into a low or binary signal, which is then transformed and amplified, and then outputs an electrical signal proportional to flow and density (4-20 madc) or a frequency and pulse signal.
