RS485 output Biogas Ultrasonic Flow meter BF-3000 gas Flow meter
Flow range basic data
1) high accuracy and good stability.
Adopt industry-leading ultrasonic gas sensing technology to achieve simultaneous measurement of biogas flow and composition.
Temperature and pressure compensation function, realizing the measurement of temperature, pressure and standard flow of biogas, and calculating cumulative flow
no mechanical transmission parts, no abrasion of measuring parts, and long term accuracy.
2) strong corrosion resistance
Specially designed ceramic ultrasonic detector has super corrosion resistance at high H2S and moisture conditions.
3) unique CH4 concentration measurement function
Adapt to the biogas subsidy policy, effectively eliminate the risk of using drum air to get more subsidies.
4) low flow measurement function
To adapt to the obvious "peak valley" characteristics of gas supply process in small biogas projects
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.
Turbine flow meter liquid flows through the turbine housing causing an internal rotor to spin. As the rotor spins, an electrical signal is generated in the pickup coil. This signal is converted into engineering units (liters, cubic meters, gallons etc.) on the local display where is applicable. Optional accessory modules can be used to export the signal to other equipment. It has the features, such as high accuracy, good repeatability, convenient installation/maintenance, simple structure etc.
