Installation precautions for metal tube rotor flowmeter
Date: 2015-02-10Read: 51

When the flow rate exceeds 100m3/h water flow rate, the pressure loss is large, and the magnetic coupling principle has no leakage and high pressure resistance.

Due to the influence of certain viscosity, it is not suitable to measure high viscosity media.
Suitable for measuring the flow rate of small caliber, low velocity gases, liquids, and vapors.
High temperature resistance, up to 450 ℃Metal rotor flowmeterMetal tube float flowmeter.
Commonly used for process control instruments, with an accuracy of 1%, typically 1.5%, and a range ratio of 10:1.
Both intrinsically safe explosion-proof and explosion-proof types are available, suitable for hazardous environments.
There are various forms to choose from, such as on-site pointer type, battery type, two-wire type, 220V AC power supply type, etc.
When measuring high temperature and low temperature (below -30 ℃) media, a jacket type is used, which is not suitable for measuring media with large density changes.
It is not suitable to measure the flow rate of pulsating media (such as the outlet of a metering pump). For gases, this meter does not have temperature and pressure compensation and needs to be considered separately.
When multiple instruments are densely installed or carbon steel process pipelines pass near the instruments, a distance of at least 100mm should be maintained from the instruments to avoid magnetic field interference.
When measuring the flow rate of media containing a large amount of ferromagnetic particles, a magnetic filter should be installed in front of the instrument and regularly purged.
If using instruments in explosion-proof environments, the round shell M4 indicator should be selected.
The metal tube float flowmeter does not have high requirements for the straight pipe section, generally the first 5D and the second 250mm are sufficient.
The high and low alarm of a flowmeter is generally in the form of an open collector OC gate, which requires an external relay for current amplification. Alternatively, a relay output type can be selected, with a contact capacity of 1A@30VDC or 0.2@250VAC The application of metal rotor flow meters is becoming increasingly widespread.
