Stormwater Pump Lift Station Radar Liquid Level Measurement______________________________________________________ When a California municipality needed reliable level measurement of their large stormwater lift station, they turned to Flowline. Located under a freeway intersection, the pump station collects, holds and then transfers the stormwater run-off from eight multi-lane highway segments above. During peak rain events, the 60′ deep vault can receive a few thousand gallons per minute along with trash, road debris, chemicals and particulates. The IC&E manager said, “We’ve tried several level sensor types here, and they’ve all had reliability or maintenance issues. I need a reliable, non-contact level sensor that maintenance-free. Additionally, it must be intrinsically safe and configurable above ground so my team can quickly verify its function.” For these reasons, Flowline suggested our 26 GHz radar sensor that’s extremely reliable, and comes with a remote display for placement in their panel. The radar sensor provides reliable level data to the SCADA which monitors the vault and controls the two lead-lag pumps. Flowline is reliable level measurement. |
Geothermal HVAC Cistern Ultrasonic Level Measurement _________________________________________________________________ When a Northeastern high school needed reliable level measurement of their geothermal HVAC cisterns, they turned to Flowline. The open loop system pumps cistern groundwater through the buildings, where it either absorbs or transfers heat based on the temperature, and then recirculates it back to the cistern. A HVAC contractor determined that the cisterns did not have enough groundwater to support the required flow rates, and they had to be periodically refilled with well water. To do so, they needed to add level measurement, a fill valve and relay control to each cistern. Finally, the I&C engineer was concerned over condensation and turbulence in the cisterns. For these reasons, Flowline suggested our reflective ultrasonic level sensors that are unaffected by condensation, installed in a standpipe to dampen turbulence. The ultrasonic sensors provide reliable level data to the controllers, which monitor the cisterns and automatically refill them when low. Flowline is reliable level measurement. |
Automotive Paint Mix Tank Ultrasonic Level Measurement _________________________________________________________________ When a Pacific Rim automative manufacturer needed reliable level measurement of their paint mix tanks, they turned to Flowline. The company continuously batches, blends and pumps nine colors through twenty-seven mix tanks to their robotic spray lines. The acrylic polyurethane paint is viscous, coating and flammable, and it becomes very agitated during blending. The mix tank OEM required reliable, non-contact level measurement with intrinsic safety, a metal enclosure and push button display for sensor configuration. For these reasons, Flowline suggested our EchoTouch intrinsically safe ultrasonic level sensor. The ultrasonic sensors provide reliable level data to the PLC, which monitors each tank and controls paint batch make up and pump transfer. Flowline is reliable level measurement. |
