Metering performance requirements Accuracy level Table 2-4 is the accuracy grade series of the vortex flowmeter. The accuracy grade should be clearly indicated on the flowmeter product manual and the nameplate of the flowmeter. Level of accuracy 0.5 1 1.5 2 2.5 Maximum allowable error qt≤q≤qmax ±0.5% ±1.0% ±1.5% ±2.0% ±2.5% qmin≤q≤qt ±1.0% ±2.0% ±3.0% […]

In addition to the correct instrument selection and installation according to the user’s given process parameters, and the installation meets the specified requirements, on-site adjustment is also a key issue. 1.On-site installation is completed and the inspection before power-on and current flow (1) There should be no leakage in the flanges, valves, pressure measuring holes,

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
