Using Inverters To Protect Sewage Mains

In this article we review how the use of inverters can reduce the mechanical stresses on pipework leading to premature failures and bursts. Inverters control the speed of pumps and in these applications, centrifugal pumps, which allow the control of pressure. The pump affinity laws state that the pressure generated by a centrifugal pump is proportional to the square of the pump’s speed. The measurement of mains pressures using ‘high speed’ (high sampling rate) pressure…
