VM 2 1/2" Digital Flow Gauge c/w Black Case Product Code: DFGMETBC


The DFGMETBC Digital Flow Gauge is designed to provide a digital flow read out when coupled to a hydrant standpipe. The Digital Flow Gauge comes supplied with a static assembly, which is used to measure static pressure at the hydrant standpipe. The equipment can be used for various applications to satisfy a number of sector requirements when it comes to assessing flow and pressure readings of both hydrant outlets and wet risers, investigating ageing conditions and incidents of overloading of water distribution systems. It can also help assist in determining leaks. Typical sectors would include; Fire Brigades, Water Companies, Associated Fire Protection Services.
