Ultrasonic biogas flow meter for Household use 

This item using the latest international technology ultrasonic gas flow measurement gas flow, and skilfully used to analyze CH4 in the biogas, achieve simultaneously measurement of gas flow rate and composition. The technology has been applied for national invention patents, and the implementation of the PCT international patent protection.

The only international gas flow can be measured simultaneously, ingredients domestic gas meter

Features
1. Basic functions: gas flow measurement and calculate the cumulative flow.
2. 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
3. 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
4. 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
5. CH4 concentration measurement functions
6. Charging functions: to achieve through the IC card billing, internal corrosion off valve shut-off valve to achieve arrears
7. 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
