LWQ Gas Turbine Flowmeter - Gas Turbine Flowmeter

Summary

Type LWQ gas turbine flowmeter is used to measure all kinds of fuel gas and some other kinds of gas in industrial field, like natural gas,city gas,LPG, propane, butane, air, nitrogen and so on. The instrument has high precision and good repetition,especially for tradement measure.

Working principle of type LWQ gas turbine fiowmeter: the gas measured go through into the instrument, The cross-section of the diversion-accelerated contraction,then by the import channel on the role of turbine vanes, making it rotating.And measured the volume of gas is proportional to the turbine rotation,The multi-stage gear reducer and the magnetic coupling to convey to the counter,showing the volume of the measured gas.

The instrument can equip HF or LF pulse transmitter-distributor , it also can equip volume-correction instrument(including Temp.&Press Sensor), to,the standard volume of the gas through the flowmeter can be showed by the volume-correction instrument.

Pulse transmitter-distributor

The turbine flowmeter can equip a LF transmitter-distributor which stick on a counter, reinstall or exchange without opening the counter.

JD-600 Volume-correction instrument

Mainly functions and features

·Get data disposal cell, press sensor and Temp. sensor together,The scene in real-time temperature and press compensation and compression factor correction automatically, measuring the standard volume flow of the gas and the standard volume gross of the gas directly.

·Machine with low power consumption: The LCD display a number of measured parameter,it can work for a long time by the battery,also have an external power supply.(DC24V)

·RS485 communication net output.

·Explosion-proof grade: Exia CT4.Explosion-proof certification NO.: GYB06446

·Strong management functions: it can to history record,alarm record, alarm of flow and temperature and press, electromagnetism alarm.All records have large numbers of information, affording information about running status to managers.

·Lots of ways of signal-out: it can be choose working conditio pulse output; corresponding instantaneous flow is 4——20mA output, The more limited flow alarm.

·Strong data saving function. It can store groups of data, including practical flow, standard flow, press, temperature, correcting coefficient, compressing coefficient, information about status alarm, date, time and so on. Time interval can be set by artificially, can be data linked to automatic meter reading system.

·If the measured gas is natural gas, use SGERC-88 way to count compression factor value.
