Abstract: the correct maintenance of metal rotameter scale method information produced by excellent flow meter, flow meter manufacturer to offer you the quotation.
1.
Metal tube flow meter belongs to the precision equipment, so in the transport, installation, storage, and use process, must take put down gently, put an end to savage transportation, stress installation, put anywhere.
Make sure indicator and the relative position of the sensor can't change.
More flow meter manufacturers choose model price quote you are welcome to inquire, is following the correct maintenance of metal rotameter scale article details.
1.
Metal tube flow meter belongs to the precision equipment, so in the transport, installation, storage, and use process, must take put down gently, put an end to savage transportation, stress installation, put anywhere.
Make sure indicator and the relative position of the sensor can't change, when the relative position changes, will directly affect the accuracy of measurement instrument.
2.
Metal pipe flow meter is usually needs no maintenance.
But in the process of long-term use, pipeline inevitably have a ferromagnetic material adsorption on the float, if too many impurities, will float jammed or affect measuring precision, so the flow sensors to be clean.
If at the entrance of the flow meter is equipped with magnetic filter, but also to the magnetic filter cleaning on a regular basis.
When cleaning
flowmeter or filter must be unloaded from the pipe.
3.
Of electric remote transmission and take alarm limit switch meter before use, open the cover, according to the instruction manual correct connection.
Unscrew the limit switch for alarm type of screw, the user according to the need to set limit alarm position, and tightening the screws, used after recovery.
4.
When used for gas measurement, should guarantee the pipeline pressure is not less than five times the pressure loss, to ensure that float work stability.
Generally measuring instrument equipped with gas damper, reduce the float shocks to the largest extent.
To further ensure the stability of the float, can be in the export of flow meters installed a throttle valve or proper orifice.
5.
Metal tube flow meter when used, should slowly open and close the valve, in order to avoid the damage of instrument.
If open flow timing, no pressure or due to the pipe system has not yet reached instrument using normal working pressure, must be slowly open the valve, until the system is normal, the instrument can use, otherwise easy to cause a pointer to beat or float suddenly hit and damage phenomenon.
6.
Users, if be density and water will not flow at the same time, or the parameters of the gas being measured and the manufacturer shall not working state and at the same time for flow meter reading value for conversion, see correction conversion method.
Above is all there is in this article, you are welcome to inquire me manufacturer flowmeter selection, quotation, etc.
