Operational Startup
The following practices should be observed when installing and starting the meter .
MAKE SURE THAT GAS FLOW HAS BEEN SHUT OFF AND PRESSURE IN THE LINE RELEASED BEFORE ATTEMPTING TO
INSTALL THE METER IN AN EXISTING SYSTEM.
1 . After meter installation, close the isolation valves and open the bypass valve .
2 . Open the upstream isolating valve slowly to eliminate hydraulic shock while charging the meter with gas . Open the valve
to full open .
3 . Open the downstream isolating valve to permit the meter to operate .
4 . Close the bypass valve to a full off position .
5 . Adjust the downstream valve to provide the required flow rate through the meter .
OTEE: N The downstream valve may be used as a control valve .
CALIBRATION
The meter is calibrated on clean, dry air at the factory and tagged with a K factor (pulses per cubic foot) . All attached
electronics have been calibrated to match the flow meter’s K factor . Ensure that the mating factory display is configured to the
proper operating pressures and temperatures of your application . The B142 meter can be re-calibrated by any conventional
meter proving processes used to calibrate standard meters .
The following graphs show how the capacities of the flow meters vary with pressure variations . Separate graphs are provided
for high, medium and low flow ranges .
