1, the introduction of LWQ
LW Q series of gas turbine flowmeter is to draw on the domestic and foreign advanced technology and optimization design of the flow meter, thegas mechanics, fluid mechanics, electromagnetics theory and self developed gas temperature, pressure, flow sensor and intelligent flow totalizer in one of the new generation of high precision, high reliability and precision measuring instruments, has the advantages of low pressure the excellent performance and high pressure measurement, signal output flowdisturbance and low sensitivity, measurement is widely used in natural gas,coal gas, liquefied petroleum gas, light hydrocarbon gas and other gases
2, the characteristics of the LWQ product
1) using a new type of sensor, the initial low flow, low pressure loss, anti vibration and anti pulsating flow performance is good, not easy tocorrosion, good reliability, long service life.
2) integrated chip uses new MCU with high performance, high computing accuracy, the powerful, superior performance.
3) using micro power advanced high-tech, low power dissipation of the whole machine. Not only can be used in battery powered operation, but also by the external power supply operation.
4) by flow frequency signal, which can be divided into eight automaticinstrument coefficient linear correction, according to user needs to improve calculation precision instrument.
5) using EEPROM data storage technology, the storage and query functions of historical data, three kinds of historical data record method for the user to choose.
6) flow meter which can rotate 180 degrees, the installation is simple and convenient to use.
7) high accuracy, generally up to ± 1.5%R,± 1.0%R.
8) with good reproducibility, short-term repeatability can reach 0.05% ~ 0.2%, it is because of its good repeatability, trade settlement in the meter ispreferred.
9) can be detected by detection of gas temperature, pressure and flow,energy flow of automatic tracking compensation, and display the standard condition (Pn=101.325KPa, Tn=293.15K) gas flow: real-time data querytemperature, pressure, time, date, etc..
