British designed & built OEM Thermal Gas Mass Flowmeter
The new CMF flowmeter has ranges from 0-10 cm3/min to 0-100 litre/min and first deliveries have an overall specification of +/-3% Full Scale, including temperature coefficients for ambient and gas temperatures from 15 to 60degC.Chell's new CMF Thermal Mass Flowmeter for OEM's
Thermal gas mass flowmeters provide far more robust flow data than any displacement or hot-wire based flow transducers due to their greater and intrinsic thermal stability. Volumetric flow as indicated by a rotameter variable area type flowmeter will have far greater errors.
Modest pricing creates a viable alternative to variable area flowmeters and, for the first time, provide their users with flow data at least 5 times more accurate and with an electrical output for control or data logging.

Required components include a flow meter that measures gallons per minute (GPM), and a pair of temperature sensors, one installed on the main supply and return water lines, be it a hot water (boiler) or chilled water (chiller) plant.

Using these sensors, along with an associated flow meter, we can determine how much energy is captured as the water moves through the tank and out to the home. Additional DataNab sensors note the tank temperature, providing clarity on when the PCM
How about this go drive under low hung High Tension Power Transmission Lines and see what happens to a new vehicle (electric brakes, electric power assisted steering, electric power assisted brakes, "fly by wire", electric brake pedals,
The Tenma SPL meter can measure SPL in the A and C scale. I recorded measurements in the A scale, notated as dBA. The SPL was measured at 10cm from the side of the center fan (or where the center fan would be). This allowed for a measurement position
blogcarparts: What is a Mass Air Flow Sensor?
The vane meter is not used as often as the hot wire because it restricts airflow, the moving parts wear easier, and finding a space to mount it is difficult. On the other hand, the hot wire style has minimal airflow resistance, it’s smaller, it has no moving parts that wear, and it responds very quickly to changes in air flow.
