When a Southern California water district needed reliable level measurement of their diesel storage tanks, they turned to Flowline. Eight of their pump lift stations are remotely located and generators are required for emergency back up power. Each generator has a 2,000 gallon diesel tank, and the level in each tank is monitored to schedule truck resupply. Their previous float level transmitters were unreliable because the floats would often become stuck in the high level condition. For this reason, Flowline suggested the use of our guided wave radar sensors which are unaffected by the coating characteristics of fuel oil. The guided wave sensor provides continuous level data to the SCADA, which in turn, reports resupply and alarm conditions to the municipal operators. The rugged sensor is constructed of 316L with an aluminum enclosure, and is ideal for metal tank applications. Flowline is reliable level measurement.
