Turbine flow meter is absorbing the advanced technology of domestic and foreign flow meter after optimization design,
combining gas mechanics, fluid mechanics, electromagnetism and other theories, which is researched and developed by
ourselves as a new generation of high-precision, high-reliability gas precision measuring instrument integrating temperature,
pressure, flow sensor and intelligent flow totalizer, with outstanding low and high pressure metering performance, multiple
signal output modes and low sensitivity to fluid disturbance, it is widely used in the metering of natural gas, coal gas, liquefied
gas, light hydrocarbon gas and other gases.

· It can detect the temperature, pressure and flow rate of measured gas, can carry out automatic tracking compensation
of the flow rate, and display the accumulated volume of the target gas (PB=101.325KPA,TB=293.15K); real-time query of
the temperature and pressure values.· Wide flow rate range (QMAX/QMIN≥20:1), good repeatability, high accuracy
(up to level 1.0), low pressure loss, low start-up flow rate of 0.6M3/H.
· The instrument has explosion-proof and protection function, the explosion-proof mark is EXDIIBT6, EXIAIICT6, and the
protection level is IP65.
· The system works with low power consumption, and a 3.2V 10AH lithium battery can be used continuously for more
than 3 years.
· Instrument coefficients and cumulative flow rate values will not be lost for ten years after power down.
· High accuracy, generally can reach ±1.5%, high accuracy can reach ±1.0%.
· Good repeatability, short-term repeatability can reach 0.05%R~0.2%R, it is because of the good repeatability,
preferred flow meter in trade settlements.
