Features

Electric supply installation and requirements

calGFR requires a 230Vac 50Hz electric supply, with a maximum current absorption of 4A.

Range of measurement
calGFR has been designed to check and calibrate gas flow meters under the following conditions:

Type of fluid: non-corrosive gases
Flow-rate range: 0 nm3/h to 10nm3/h.
Temperature range: 10-40°C
Pressure range: 10-100mbar

The measurement of the gas volume is performed by the volumetric counter, that includes a pulse generator which pulses are detected by the software, converting them in gas volume. The gas pressure, the barometric pressure and the gas temperature values are also read by the software and used to correct the gas volume measurement to standard units. From the gas volume value and the time (calculated using the clock of the control notebook), the software calculates the standard flow rate. The integration time considered in the calculation is a parameter settable by the operator. calGFR has to be connected downstream the device under calibration using flexible hoses and a suitable system to adjust the gas flow rate has to be added downstream calGFR.
