Mass Burette Type Flow Detector
made-to-order
FX-1100シリーズ
The mass burette type flow detector, when used in combination with the FM-3100 flow meter, detects the liquid level of fuel filled in a precision burette tube using a high-precision differential pressure gauge mounted at the bottom, and directly measures the fuel flow rate by weight from the change in pressure.
It is highly accurate without the need for temperature and specific gravity correction calculations, and it is extremely resistant to bubble intrusion, allowing for fuel consumption measurements in tests such as chassis dynamometers and engine benches. You can choose from three models according to the measurement range and application.
The pressure signal from the differential pressure detector opens the solenoid valve (V1) when the liquid level drops below L3, allowing the liquid to fill. When the liquid level reaches L2, V1 closes, and after the set liquid level stabilization time has elapsed, it begins measuring the instantaneous flow rate. As the liquid flows out from the flow detector and the liquid level drops from L2, the output of the differential pressure detector also changes according to the weight of the outflowing liquid.
From this change, the FM-3100 (module integrated for FM-0331 FX) digital flow meter can display the flow rate as a direct digital readout of weight.
The air vent port is a port for allowing air generated inside the detector to flow in and out with the inflow and outflow of liquid.
It is usually piped to the gas layer of the liquid supply tank.
Additionally, by connecting compressed air at a constant pressure to this port, fluid can be pressurized and pumped into the specimen. Pressurizing and pumping does not affect flow measurement.
