ltrasonic Biogas Flow Meter BF-3000

Ø  Production description

It adopts industry-leading ultrasonic gas sensing technology for flow measurement in large, medium and small biogas engineering stations, and collects on-site pressure and temperature. Its unique methane concentration measurement function can provide an optimized measurement scheme for flow measurement, acceptance and supervision in the biogas engineering station.

Functional characteristics:

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

Ø  Product Features:

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.



Product Description

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.


Product features

1.The impeller of the sensor is made of special alloy bearing, which has good wear resistance and long precision.
2.Simple and firm structure, easy to assemble and disassemble and clean.
3.Multi point nonlinear correction, high precision, data power down for 10 years.
4.A variety of signal output, suitable for different occasions.
