Griffco Borosilicate Glass Calibration Cylinders are designed to enhance the performance of chemical feed systems by providing a verification of the flow rate of the chemical feed pump.
Constructed of borosilicate glass and a choice of 5 end cap materials, (PVC, PTFE, PVDF, 316 SS, A20) these cylinders are suitable for use with most chemicals.
6 sizes; 100 mL, 200 mL, 500 mL, 1000 mL, 2000 mL, 4000 mL.

Operation:
Griffco calibration cylinders are installed in the suction line to the chemical metering pump. Two isolating valves, (not supplied) must be install in the suction line as per the drawing below. The top of the cylinder should be vented back to the storage tank or to drain.
Fill the cylinder to the top mark then close the valve from the chemical tank. Switch on the chemical feed pump and draw down the chemical in the cylinder for 30 seconds. Switch the pump off. The reading on the left side of the cylinder is a direct readout of USgph.
Alternatively, observe the volume withdrawn on the ml scale. To convert to LPH or GPH use this formula:
LPH = (volume÷draw time) x 3.6
GPH = (volume÷draw time) x 0.952
Note: Max. cylinder pressure is 15 psi.
