Installation of flow meter
Before installation, the pipeline must be blown clean to prevent residual iron filings from affecting the normal operation of the flowmeter.
Before installation, if the turbine can rotate flexibly without irregular noise when blown by a small airflow, and the ink injection display is normal, then the flowmeter can be installed and used.
When installing the flowmeter, a sealing gasket should be added in the middle of the flange of the pipeline.
A filter should be installed in front of the flowmeter, and an oil filter should be installed in areas with dirty air. Before placing an order, users can also place an order with our company. It is strictly prohibited to directly connect the filter and flowmeter.
The flowmeter should be equipped with shut-off valves before and after installation.
There should be no protrusions on the inner diameter of the pipeline at the flange connection.
When installing the flowmeter, it is strictly prohibited to directly weld at its inlet and outlet flanges to avoid burning out the internal parts of the flowmeter.
The flowmeter should be installed in a location that is easy to maintain, free from strong electromagnetic interference, mechanical vibration, and thermal radiation.
Flow meters should not be used in situations where flow is frequently interrupted and there is strong pulsating flow or pressure pulsation.
When installing the flowmeter outdoors, there should be a cover on the upper part to prevent rainwater from entering and direct sunlight from affecting the service life of the flowmeter.
The flow meter can be installed horizontally or vertically, and the direction of fluid flow should be consistent with the direction marked on the housing. A straight pipe section of not less than 10Dn should be ensured upstream of the flow meter, and a straight pipe section of not less than 5Dn should be ensured behind the meter.
