A filter should be installed in front of the flowmeter, and the arrows on the two meter bodies should point in the same direction as the flow.

*When the measured liquid contains gas, a gas separator should be installed in front of the flowmeter.

*Regardless of whether the pipeline is installed vertically or horizontally, the waist wheel axis of the flowmeter should be installed in a horizontal position (i.e. the dial should be perpendicular to the ground).

*Before installing the flowmeter, the pipeline needs to be flushed. During flushing, a straight pipe section (replacing the position of the flowmeter) should be used to prevent welding slag, debris, etc. from entering the flowmeter.

*It is strictly prohibited to use water to calibrate flow meters made of cast iron or steel materials.

*The flow rate of the flowmeter should not exceed the technical requirements during use, and it is preferable for the flowmeter to operate normally at a high flow rate of 70-80%.

*If the measured liquid has chemical corrosiveness, a stainless steel flowmeter should be selected. If the corrosiveness is strong, a 0Crl8Ni12MO2Ti flowmeter should be selected.

*If it is difficult to see the reading clearly when the flowmeter is installed correctly, the counter can be rotated 180 or 90 degrees.

*The throttle valve should be installed at the inlet of the flowmeter, and the on-off valve should be installed at the outlet. When using the on-off valve, it should be started slowly and not suddenly opened.

*It is strictly prohibited to use sweeping steam through flow meters.

*In the continuous use department, a bypass pipeline needs to be added to the flow meter.
