Pressure Measurement Bench
 
Description of Pressure Measurement Bench
 
	- The
	apparatus has been designed to allow the suction pressure or delivery 
	pressure of a diaphragm pump to be measured on sloping or vertical 
	manometers and Bourdon gauges, for comparison; and to investigate the 
	calibration and internal workings of a Bourdon gauge.
-  The
	apparatus comprises of two units: the manometer and gauge assembly and 
	the calibration of a pressure gauge assembly. The internal mechanism of 
	the gauge is clearly visible through the transparent dial. During test, 
	calibration weights are placed onto the loading platform, which is an 
	integral part of the piston assembly. All air is expelled from the 
	system through a purge hole in the upper part of the cylinder
