The flowmeter should generally be installed behind the valve, because the medium may appear two-phase after passing through the valve, the pipe is not full, and the flow phase is unstable. These conditions will greatly affect the measurement accuracy of the flowmeter, so the flowmeter should be installed in front of the valve. But because […]

Although the flow meter has been strictly tested before leaving the factory, because of changes in the environment, installation, running condition, etc, errors will occur, and test operation needs to be done using the following methods: Test using standard flow measure equipment Conversion between two flow media The primary test medium in the factory is

When choosing a magnetic flow meter, the following factors may take into consideration: 1 Fluid types 2 Accuracy 3 Density 4 Viscosity 5 Electrical conductivity 6 Contaminants 7 Flow range 8 Fluid temperature 9 Fluid pressure 10 Pressure loss 11 Pipe diameter   You can also download this checklist form.   https://drive.google.com/file/d/1bUdTYPWLu25eJf1orMPRe5vnZnCF9Dr7/view?usp=sharing

Target Mode Flow meter consists of measure tube, pressure target, sensor part (include flow strength sensor, pressure sensor, and temperature sensor), transition part (variable types based on temperature, pressure), integration microcomputer (include an LCD display and output part). The structure is shown below: Target Sensor Part Measurement Tube Transition Part Integration Microcomputer

Target flow meter usually installed after the pump. As there should be no excessive pressure drop at the pump inlet (in front of the pump). Installed a flow meter will always increase the pressure drop. It may also increase the length of the pipe and increase the complexity of the pipe. Moreover, the pipe in

Although the flow meter was set zero before leaving the factory, it may be offset because of the inevitable slight impact on transport. If the flow meter does not display zero when the flow velocity is zero, zero offsets occur and zero set operation has to be done: Close the behind valve. Turn on the

To find out the value of the “K factor” in a turbine flowmeter device, the manufacturer bypasses a defined volume of the liquid via the meter and calculates the pulses produced by the meter. The sum of all pulses divided by the liquid’s known volume provides the “K factor quantity.” For a turbine flowmeter, the

Electromagnetic flowmeter is used to measure the volume flow of conductive liquid medium with conductivity greater than 5μs/cm. To know the fluid conductivity is important. The conductivity of gas, oil, and most organic liquids is much lower than 5uS/cm, and they are not conductive. That’s the reason it can’t use the magnetic flowmeter to measure.

The turbine flow meters are widely used in liquid and gas measurement. The gas turbine flow meters catalog: https://www2.slideshare.net/MichaelSun5/gas-turbine-flow-meter-239944663   The liquid turbine flow meters catalog: https://www2.slideshare.net/MichaelSun5/liquid-turbine-flow-meter-89634185

When installation in vertical position, medium flow direction is should from down to up. The two ends of the flowmeter installation must be sealed and no leakage. During installation, avoid a strong impact on the flow meter, which may damage the instrument or cause serious zero drift.
