When a US municipality needed reliable level measurement of their polymer mixing tanks, they turned to Flowline. Polymer is widely used in wastewater treatment to coagulate suspended solids, producing large curds of floc or solid material, which can then be easily removed from the process. Granulated or emulsive polymer is diluted with water, blended, and injected into the process with a high viscosity metering or variable speed pump. A polymer mixing tank typically holds 1-2 days of product before a new batch must be made up, and level measurement of this sticky media is critical to the operator. For this reason, Flowline suggested the use of a non-contact ultrasonic level sensor. The result is reliable polymer level measurement. Here, an EchoPod ultrasonic level transmitter is safely mounted above the polymer solution. Despite being located next to the tank side wall and mixer shaft, the sensor’s measurement is unaffected due to its industry leading 2″ (5 cm) beam width. The two-wire, 4-20 mA signal output is connected to the SCADA for level monitoring, and the integral relays actuate a high and low alarm. Flowline is reliable level measurement.
