CALIBRATION CYLINDER – INSTALLATION GUIDE
LOCATION:
Install the calibration cylinder as shown in Figure 1. The cylinders must be installed in
the suction piping in a vertical position and as close as possible to the suction tank.
Remember the location should make allowance for sufficient free space around the
calibration cylinder for easy reading of graduations.
PIPING:
It is essential that the size of the pipe to the calibration cylinder be the same size as
the suction piping and cylinder inlet connection. Under-sized pipe work will cause
suction losses and, hence, affect calibration accuracy.
We strongly recommend that the use of full-flow ball valves to give consistent system
throughput and rapid open and shut operation – an important feature when checking
calibrations.
Piping should be air-tight and suitably supported at regular intervals.
An overflow/venting line should be connected between the top of the calibration
cylinder and the supply tank.
CAUTION: NEVER USE THE CYLINDER ON THE DISCHARGE SIDE OF ANY
PUMP.
