LQW gas turbine flowmeter

This product has been inspected and approved by the national explosion-proof product quality inspection department in accordance with the standards of GB3836.2000 "Electrical Equipment for Explosive Gas Environments Part 1: General Requirements", GB3836.2-2000 "Electrical Equipment for Explosive Gas Environments Part 2: Explosion proof Type" d "", and GB3836.4-2000 "Electrical Equipment for Explosive Gas Environments Part 4: Intrinsic Safety Type" i ". The explosion-proof marks are Exd Ⅱ BT4 (Explosion proof Type) and Exia Ⅱ CT4 (Intrinsic Safety Type). Applicable to Zone 1 and Zone 2 hazardous areas containing explosive gas mixtures of Class IIA, IIB, and IIC temperature groups T1 to T4 (only intrinsic safety type).
Product features;
High quality alloy turbine, with higher stability and corrosion resistance, imported high-quality special bearings, long service life, isolated metering chamber and ventilation chamber, ensuring the safety of the instrument. It can detect the temperature, pressure and flow rate of the measured gas, automatically track and compensate for the flow rate, and display the accumulated gas volume under standard conditions (Pb=101.325KPa, Tb=293.15K); Real time temperature and pressure values can be queried, with a wide flow range (Qmax/Qmin ≥ 20:1), good repeatability, high accuracy (up to 1.0 level), low pressure loss, low starting flow rate, and intelligent instrument coefficient multi-point nonlinear correction. Built in pressure and temperature sensors have high safety performance, compact structure, and beautiful appearance. The instrument has explosion-proof and protective functions, with explosion-proof marks of Exd Ⅱ BT4 and Exia Ⅱ CT4, and a protection level of IP65. The system operates with low power consumption, and a 3.2V10AH lithium battery can be continuously used for more than 3 years. The instrument coefficient and cumulative flow value will not lose power for ten years without losing power
