Domestic gas Roots flowmeter, gas Roots flowmeter, LLQ gas Roots flowmeter

Description :

　　Domestic gas Roots flowmeter, gas Roots flowmeter, LLQ gas Roots flowmeter

　　This product mainly consists of three parts: measuring chamber, sealed coupling, and counter. It can indicate cumulative flow and instantaneous flow on site, equipped with a transmitter and intelligent flow controller, and can achieve remote measurement and control.

　　1、 Characteristics

　　1. Reliable operation and long lifespan. The waist wheel rotor with high-precision machining and balance, surface high hardness treatment, no contact and wear, and good lubrication environment ensure the long-term reliable operation of the flowmeter.

　　2. Wide flow range, low starting flow.

　　3. High precision and reliable measurement performance. No need to adjust accuracy, unaffected by changes in the measurement medium conditions.

　　4. Dual power supply function, which can achieve low power consumption by using built-in lithium batteries for power supply, as well as bidirectional two-wire power supply and output signal mode, and also has RS485 communication function.

　　5. Built in temperature and pressure compensation can directly compensate for real-time density and calculate the standard volumetric flow rate of the medium.

　　6. The intelligent integrated processing inside the integrator ensures stable and reliable measurement under external interference, and has process reliability.

　　7. It has floating-point operations and automatic correction of multi terminal instrument coefficients, as well as fault self diagnosis and alarm functions.

　　8. The large screen LCD displays various parameters such as total volume, flow rate, temperature, pressure, density, and battery capacity, and has a display function for fault alarms.

　　9. It has real-time data storage function, which can prevent data loss during battery replacement or sudden power failure; In the event of a power outage, internal data can be saved and a large amount of historical data during operation can be queried.

　　2、 Usage conditions

　　a. Environmental temperature: -25 ℃ to+50 ℃

　　b. Medium temperature: -20 ℃~+60 ℃

　　c. Relative humidity: 5% to 95%

　　d. Atmospheric pressure: 86KPa~106Kpa

　　3、 Installation requirements:

　　1. Environmental conditions: There are no corrosive fluids in the surrounding area, low mechanical vibration, minimal dust, and a location away from heat sources. For intelligent flow meters equipped with volume correction devices, there should also be an environment that complies with regulations.

　　2. Environmental temperature: generally not exceeding the range of -20 to+80 ℃.

　　3. Pipeline conditions: Before installing the flowmeter, the pipeline must be cleaned and purged to remove all debris, rust, and dirt. The connecting pipeline should generally be coaxial with the inlet and outlet of the flowmeter, and there should be no protruding objects protruding from the pipe wall into the pipeline. Flow meters should be installed without stress, taking into account the pipeline stress caused by operating temperature.
