Flow meter

In the measurement and control of industrial production processes such as petrochemicals and fertilizers, a large number of electromagnetic flowmeters that can solve the problem of medium corrosion are used. However, in the production sites of these industries, there are often explosive gases and vapors from flammable liquids. Therefore, explosion-proof electromagnetic flowmeters are required. Regarding […]

As with all newly purchased meters, when the mass flow meter ordered arrives, the unpacking inspection should be carried out first. Usually, the unpacking inspection should be carried out according to the following steps: First, visually inspect the outer packing box. Before unpacking, check the outer packing box of the flowmeter. Because abnormal phenomena may

A turbine flowmeter is more sensitive to the influence of the velocity distribution of the inlet fluid. The inlet flow state depends on the piping structure at the inlet of the flow meter. In principle, it is required to have a straight pipe section long enough to eliminate the symmetrical and stable cross-section of the

A turbine flowmeter is a speed-type instrument. The change of density will increase or decrease the rotating torque acting on the impeller proportionally, thereby affecting the displayed volume flow. In the case of measuring liquid, because the density of the liquid changes little, and the bearing friction torque is as small as possible in the

There are two reasons for the pressure loss of the turbine flowmeter. One is part of the pressure loss caused by the mechanical resistance of the turbine rotor to the kinetic energy of the fluid. The greater the flow, the higher the speed of the turbine, the greater the mechanical resistance, and the greater the

The development of flow measurement technology and the application demand in the national economy are always interdependent. In a sense, application and demand are the driving force to promote the development of flow measurement technology. Although there are many types and specifications of flow meters so far, with the rapid development of social production, the

In order to ensure the measurement accuracy of the mass flowmeter and long-term stable and regular work, the mass flowmeter should be installed reasonably, used correctly, and strengthened daily maintenance and management. Among various types of flow meters, Coriolis mass flow meters are the most widely used. This chapter will discuss the daily maintenance and
