FM-21 PIPE NETWORK APPARATUS

The bench comprises a water storage sump tank from which a self priming pump delivers water to the system. It incorporates a volumetric measuring tank, the water level being indicated by a remote sight tube and scale on the bench front. A dump valve in the base returns the measured water to the sump tank for recycling. The top of the bench is fitted with a metal supporting frame for the pipe networks and the inlet manifold. Five pipe lengths in three diameters are supplied. A wide range of series, parallel and mixed configurations is possible using the interconnecting fittings supplied. Fittings are readily assembled. Pressure differences between points in the system are measured with the U tube manometers - mercury for the higher differences and water for the lower. Pressure tapping points are provided in the fittings to which connection is made via probes and flexible tubes. The interchangeable lengths of pipe and interconnecting fittings are stored on a board attached to one end of the bench.

• Consequent to its hazardous nature many technicians prefer not to use mercury or its use may be prohibited in the laboratory. With this in mind we offers a hand held, portable, battery operated pressure meter which is capable of measuring pressures of air or water from 0-2000mBar (0-1500mm Hg).
