This equipment allows the moment caused by a fluid thrust on a wholly or partially submerged plane surface to be measured directly.

A PVC quadrant is mounted on a balance arm pivoted on knife edges which coincide with the quadrant center. When the quadrant immerses in water, there are hydrostatic forces. The balance arm has an adjustable counter balance and weights with a hanger. The quadrant is mounted on top of a clear acrylic tank which allows water to be admitted and drained to a required level by a valve. The tank rests on adjustable footings and a bull’s eye level is provided.

The tester is designed to calibrate pressure gauge.
It consists of a precision machined stainless steel piston and cylinder with calibrated weights. The weights are applied on the upper end of the piston rod to generate pressure. The assembly is mounted on adjusting screws with a bull’s eye level. The pressure gauge is connected to the cylinder, thus subject to known pressure and comparison with the gauge reading can be made. Leaking liquid from the cylinder is returned to a reservoir. The cylinder can be simply refilled with liquid from the reservoir without removing the piston.
