categories of metal tube flow meter
According to the ways of indicating the flow value, metal tube flow meter falls into two categories: on-sight display
and mote flow transducer.
Metal tube flow meter also can be classified into the following kinds as per applications:
1. on-sight display
on-sight display metal flow meter is mainly applied for the locale flow value measurement, which doesn’t need to record,
accumulate and control. This kind of flow meter doesn’t have the single exchange part. Tube may be replaced by transparent
straight arm engraved with flow value. The flow value is easy to point out when looking at the position floater stays. For
on-sight displaymetal tube flow meter of pressure up to (25~30) MPa, the flow value can be read on the magnetic loop moved together with floater on the housing.
2.mote flow transducer
Most metal tube flow meters have the requests of remote output. The mechanical movement of floater is transformed to current
or standard air pressure single. Electric mote flow transducer flow meter can be ordinary type and explosion-proof type.
Since electric mote flow transducer flow meter has overcome the difficulty of explosion-proof requests, application of gas
mote flow transducer is on the decrease.
3. Ordinary type, anti-corrosion type and intelligent type
Ordinary type has the widest range of application, mainly applied for industrial process controlling system or relatively
high temperature and pressure circumstance. It mainly measure air, water and oil. Anti-corrosion type usually use F40, F4 PVDF to protect the metal from corrosion.
4.Jacketed insulation flow meter
Jacketed insulation metal tube flow meter takes advantages of hot water or heat steam to achieve the purpose of heat
Electric mote flow transducer usually has explosion-proof and Benan design structure for situation having explosion-proof
As for the measured fluid, metal tube flow meter is suitable for fluids, gases and steam.
When it comes to the flow value, it falls into full flow type and bypass flow type.
