Flow measurement range :0-4 .0 m3 / h Flow measurement accuracy: 1.5 CH4 measurement range :30-100% CH4 measurement error: <5% Working pressure: less than 100KPA Power supply: 3 AA batteries (1.5V) Explosion-proof grade: Ex ibIIAT4 Gb Mounting interface: M30 * 2.0
Basic functions: gas flow measurement and calculate the cumulative flow
Corrosion resistance: the traditional film form at high H2S and moisture conditions susceptible to corrosion damage, ultrasonic gas flow meter without coating, ceramic ultrasonic probe using a special probe, superior corrosion resistance
Anti-pressure shocks: the traditional film table bearing capacity is poor, and easily damaged when the pressure fluctuations, ultrasonic gas flow meter without coating, can withstand high pressure shocks
Temperature compensation function: the traditional film form without temperature measurement function, the winter (0 degrees), summer (37 degrees) measurement error of 15%, ultrasonic gas flow meter built-in temperature sensor
CH4 concentration measurement functions
Charging functions: to achieve through the IC card billing, internal corrosion off valve shut-off valve to achieve arrears
Safety features: the use of ultrasonic can be low flow measurement, bi-directional measurement advantages, you can determine biogas leakage and tempering, the threshold is reached automatically shut off the gas valve to ensure safety.
