Requirements for explosion-proof products when installing turbine flowmeters

In order to be used safely and normally, it should be checked whether the use environment of the explosion-proof turbine flowmeter is consistent with the user's explosion-proof requirements, and during the use of the equipment, the national requirements for the use of explosion-proof products should be strictly followed, and the user is not allowed to change the connection method of the explosion-proof system , Do not open the surface at will. The type selection is within the specified flow range, and overspeed operation is avoided to ensure the desired accuracy and normal service life. Before installing the turbine flowmeter, clean up the debris in the pipeline: debris, welding slag, stones, dust, etc. It is recommended to install a filter with a 5 micron mesh in the upstream to prevent droplets and sand. When the turbine flowmeter is put into operation, the front valve should be opened slowly first, and then the rear valve should be opened to prevent the turbine from being damaged by the impact of the instantaneous air flow. Lubricating oil should be operated according to the notice board, and the frequency of refueling depends on the cleanliness of the temperament, generally 2-3 times a year. The flowmeter may be damaged due to pressure testing, purging pipes or exhaust to cause overspeed operation of the turbine, and operation of the turbine in reverse flow. It is not allowed to open the front of the flowmeter at will when it is working. Change the relevant internal parameters, otherwise it will affect the normal operation of the flowmeter. Care should be taken with installing gaskets to ensure that no protrusions enter the pipes so as not to interfere with normal flow measurement.

are important in ensuring electromagnetic flow meter slurry, and the machine is utilised by everyone from endress hauser ultrasonic flow meter to low flow turbine flow meter.
