MULTIPLE COMPENSATION METHODS
Temperature and pressure automatic detection compensation, pressure automatic detection temperature setting compensation, temperature automatic detection pressure setting compensation, temperature and pressure are set compensation.
At the same time, the pressure value and temperature value of the reference state can be set by the user to meet the needs of different fields.
High precision, no zero drift, high range ratio, and good repeatability. Because the turbine flowmeter uses high-quality bearings and a unique baffle, it greatly enhances its wear resistance, and can also be measured in harsh environments without measurement distortion.
The impeller of the turbine flowmeter has an anti-corrosion effect, and the externally adopts an all-stainless steel structure, which has strong anti-magnetic interference and vibration capability, which greatly enhances the service life of the instrument.
The intelligent gas turbine flowmeter is a new generation flowmeter that integrates flow, temperature and pressure detection functions and can automatically compensate for temperature, pressure and compression factors. It is gas for petroleum, chemical, electric power, metallurgy, industrial boilers, and other industries. Ideal instrument for metrology and measurement of urban natural gas, gas pressure regulating stations and gas trade.
N2 is normally used and Nitrogen flow meter is often been requested by our customers, we often choose vortex shedding flow meter, thermal mass flow meter, gas turbine flow meters to measure nitrogen flow rate.
We choose different types of gas flow sensors according to the nitrogen flow range, user’ s pipelines, process connection (flange type or insertion type gas sensor), operation temperature and pressure, output and communication request, and power supply.
A turbine flow meter is a volume sensing device. As liquid or gas passes through the turbine housing, it causes the freely suspended turbine blades to rotate. The velocity of the turbine rotor is directly proportional to the velocity of the fluid passing through the flow meter.
Turbine flowmeters use the mechanical energy of the fluid to rotate a “pinwheel” (rotor) in the flow stream. Blades on the rotor are angled to transform energy from the flow stream into rotational energy. The rotor shaft spins on bearings. When the fluid moves faster, the rotor spins proportionally faster. Turbine flowmeters now constitute 7% of the world market.
Shaft rotation can be sensed mechanically or by detecting the movement of the blades. Blade movement is often detected magnetically, with each blade or embedded piece of metal generating a pulse. Turbine flowmeter sensors are typically located external to the flowing stream to avoid material of construction constraints that would result if wetted sensors were used. When the fluid moves faster, more pulses are generated. The transmitter processes the pulse signal to determine the flow of the fluid. Transmitters and sensing systems are available to sense flow in both the forward and reverse flow directions.
