LEVEL CONTROL SUPPLYING WATER TO ELEVATED TANK
A municipal utility in eastern Germany operates two water towers for the drinking water supply of adjacent communities. The long-distance pipeline (DN300) is operated at a pressure of 10…13 bar / 145…188.5 psi. The operator must regulate the supply to the elevated tanks to achieve the desired tank level setpoint and the pressure at the inlet must be carefully controlled so that no damage occurs to the components due to excessive differential pressures. In this application FOCUS-1 reliably controls the level as an external control variable according to the desired setpoint.
