F Bamford (Instruments) Ltd
Frank Smith was the designer of the flow switch during the Second World War. It was produced as a way of guarding large Mirrlees diesel engines against a loss of cooling water.
A range of additional flow instrumentation products were designed and added to the portfolio with temperature, pressure and level devices all manufactured to the same rugged specification. A flameproof range was also designed for use in coal mines and petro-chemical installations.
Our flow instrumentation products today include: mechanical and electronic flowmeters, flow, temperature, pressure and level switches, flow indicators and sight glasses, exhaust gas temperature monitoring systems, fibre optics shaft wear gauges.
