Description :

　　Intelligent LWQ-200 gas turbine flowmeter

　　This product adopts micro power consumption technology and spectrum analysis methods to collect data, and has developed a new structure of intelligent flowmeter.

　　1、 Product Features

　　1. High quality alloy turbine with higher flow stability and corrosion resistance;

　　2. Imported high-quality specialized bearings with long service life;

　　3. The isolation between the measuring room and the ventilation room ensures the safety of the instruments;

　　4. It can detect the temperature, pressure, and flow rate of the tested gas, automatically track and compensate for the flow rate, and display the standard state; The cumulative gas volume of Pb=101.325KPa, Tb=293.15K; Real time query of temperature and pressure values;

　　5. Wide flow range (Qmax/Qmin ≥ 20:1), good repeatability, high accuracy (up to 1.0 level), low pressure loss, low starting flow rate, up to 0.6m3/h;

　　6. Multi point nonlinear correction of intelligent instrument coefficients;

　　7. Built in pressure and temperature sensors, high safety performance, compact structure, and beautiful appearance;

　　8. The instrument has explosion-proof and protective functions, with explosion-proof markings of Exd Ⅱ BT6 and Exia Ⅱ CT6, and a protection level of IP65;

　　9. The system operates with low power consumption, and a 3.2V10AH lithium battery can be used continuously for more than 3 years;

　　10. The instrument coefficient and cumulative flow value will not be lost for ten years after power failure.

　　3、 Installation and use

　　1. External dimensions of flowmeter

　　Installation of Flow Meter 2

　　(1) Flow meters should be installed according to the flow direction markings.

　　(2) The flowmeter can be installed horizontally, vertically, or tilted at any angle.

　　(3) Please refer to the requirements for the upstream and downstream straight pipe sections

　　(4) Unless the tested medium contains larger particles or longer fibrous impurities, it is generally not necessary to install a filter.

　　(5) There should be no strong external magnetic field interference or strong mechanical vibration around the flowmeter.

　　(6) The flowmeter must be reliably grounded.
