The apparatus, which is illustrated in Fig. 1, consists of a valve base and a bronze barrel which has a precision machined bore into which fits a stainless steel piston. Calibration of Pressure Gauges is used for the calibration of the Bourdon type pressure gauge supplied with the Cussons Hydraulic Bench and other gauges of a similar rating using the dead weight method. Fitted to the valve base are two connections and a blanking plug. A connection for the pressure gauge under test is pre-fitted and supplied with a length of plastic pipe suitable for connection to the pressure gauge via the auxiliary tapping on the Hydraulics Bench. The piston is fitted with a platform which can carry calibration weights the weights supplied with the apparatus are equivalent to pressures of 0.5 bar and 1 bar. The piston and platform have a total weight equivalent to 0.5 bar pressure. A non-return connection for the water supply from the hydraulics bench is fitted on one side of the valve block. A spill-pipe is fitted into the barrel which prevents the piston being ejected by excess pressure. The Bourdon gauge, fitted on the Bench, is a simple device and normally very reliable in service. On the third side of the block is a blanking plug which is removed to allow the apparatus to be drained of water. The apparatus is mounted on a plastic base for stability. After an extended period of use, slight deviations of value are likely to occur and for "accurate" work a calibration curve for the instrument is necessary. The basic element of the gauge is a curved, elastic-metal tube, usually of brass or stainless steel, which changes its geometry when filled with fluid under pressure. This distortion is transmitted by linkage to the gauge pointer. The dead weight tester is not subject to variations and can, therefore, be used as a reliable.

The Mass Oscillations And Hammer Study Unit is provided with a constant level container connected to the water supply by means of a pipe.
In the hydraulic systems the flow variations produce two phenomena: the mass oscillation and the water hammer which are related each other but have different characteristics.
For the water hammer test, the unit is provided with a quick closing valve with manual control in order to obtain an immediate flow interruption.
The oscillation test section is made of stainless steel 3 m long provided with the valves necessary for the flow control and with two pressure measurement devices, the electric signal of which is sent to a double trace memory oscilloscope which allows to examine, in all the phases, the phenomena of mass oscillation.
The Mass Oscillations And Hammer Study Unit is available in two different solutions:
Hydraulic supply from mains
Hydraulic supply from provided with additional tank.
Experiments:
Determination of the transient pressure curve of a water hammer by means of an oscilloscope
Demonstration of the losses in the reservoir and in the balance tank
Water hammer demonstration
Mass oscillation demonstration
Visualization of oscillation characteristics in the balance pipe.
The components of this unit are pre-assembled with a compressor operating with refrigerant. A large electric moter is mounted with a control housing in a self contrained heavy duty roller cart.

The aneroid manometer consists of a metal bellows, which expands as the pressure in the cuff increases, and a mechanical amplifier that transmits this expansion through a lever to an indicator needle, which rotates around a circular, calibrated scale. A device designed to measure blood pressure consisting of an inflatable cuff that fits around a limb (arm or thigh), an inflation bulb for controlling the air pressure within the cuff, an aneroid manometer, and tubing. The manometer is hand held (portable); blood pressure measurement is taken in conjunction with a stethoscope.
