Flow meter

For many installations a periodic check of the magnetic flow meter is mandatory. A visual inspection should be the first line of defense against a faulty magnetic flow meter. The excitation coil resistance of the sensor, insulation resistance between the signal wires, grounding resistance, and other readings should match the factory standards. Moreover, the verification […]

A magnetic flowmeter will not work with demineralized water. As the electrical conductivity is not enough, a turbine flowmeter is a good choice.

Flowmeter is generally installed in a horizontal position. 1, 2, and 3 are respectively the front, behind and by-pass valves and 4 is the flow meter. L≥10D and L>=5D are respectively front and behind pipelines whose lengths are larger than 10 and 5 times of the pipe diameter respectively. Minimum pipe length (diameters): upstream lengths

When measuring the volume flow, the density has no effect. If measuring the mass flow, it has something to do with the density. Generally, an electromagnetic flowmeter is a flowmeter that measures the flow rate. The density of different liquids is different. This means to accurately measure the mass flow of different liquid flow meters.

1) The flow meter display non-zero, while the flow velocity is zero. The following reasons and solution methods may be included: Flowmeter was not installed in a strictly horizontal position. Solution: zero set operation. Flow meter has run for a long time and error occurs. Solution: zero set operation. Overloading brings zero offsets. Solution: zero

Measurement flow of liquid, gas, steam, ropy mediums, or ambulatory mediums in low, normal, or high-temperature conditions. Total quantity measurement accuracy is not less than 0.2%. High sensitivity, able to measure very low velocity below 0.8m/s. No movable part, safe and reliable. Wide measure range, bigger than 1:30. Good repeatability, generally 0.1～0.08%, fast to measure.

When the flow medium flows through the measured tube, the pressure will force on the target because of the flow kinetic energy. It is known that the pressure value forcing on the target can be expressed as： F = cd ρ v2 At / 2 where F = force on the target (N) cd = overall drag coefficient obtained from empirical

Usually, the Target flowmeter display unit has the following options: flow unit m3 flow unit t flow unit L flow unit Kg

In many instances, yearly calibrations are not necessary. If the measurement requirements are high, there are more impurities and dirt in the fluid, and the environmental conditions are poor, the electrode is fouled, which affects the measurement, cleaning, and the measurement is inaccurate after repair. It can be calibrated. If the working conditions are good
