AW-Lake Introduces High Accuracy Water Inline Ultrasonic Flow Meter; Completes Family of Flow Meters for Process Cooling Systems

Oak Creek, Wisconsin – November 8, 2021 – AW-Lake Company introduces a Water Inline (WIN) Ultrasonic Flow Meter for highly accurate and reliable flow measurement of cooling water, condensing water, and water/glycol solutions.  Designed for process cooling applications including industrial cooling circuits, the WIN Ultrasonic Flow Meter has no moving parts for long-term reliability and low maintenance costs.  By incorporating two wetted ultrasonic transducers that face each other directly in the flow tube, the ultrasonic flow meter reduces wear associated with moving parts and maximizes signal strength.

The WIN Ultrasonic Flow Meter offers very high accuracy (+1.0% of reading over 25:1 turndown, 100:1 total turndown) over a wide flow range with minimal pressure drop. An innovative flow tube design simplifies installation in limited straight runs and ensures no obstruction in the flow path.  Holding an IP67 (NEMA 6) rating, the WIN Ultrasonic Flow Meter operates safely when temporarily submerged in water.

An LCD display version comes standard with Modbus RTU communications, providing an output of flow rate, volume total, run hours, alarms, and diagnostics.  The display is detachable for remote mount installation up to five feet from the sensor.  A built-in data logger enables easy data access vis Modbus.  Units without a display come standard with analog and pulse outputs, 24V AC/DC power, one pulse, and one analog output.

The WIN Ultrasonic Flow Meter completes the AW-Lake family of flow meters for the cooling circuits market that also includes:

  • TRG Standard Turbine Flow Meter:Ideal for monitoring solvents and other viscosity fluids, these meters offer high accuracy with a millisecond response time, along with high pressure and temperature capabilities. These units have moving parts and require some maintenance.
  • FlowStat Paddle Wheel Flow Meter: Ideal for monitoring various fluids in applications such as chillers/cooling circuits and HVAC, this meter offers a fast response time with easy maintenance.  Economically priced, units use moving parts and require a full pipe.
  • Variable Area Flow Meter:Ideal for monitoring pump performance and oil or water flows through cooling systems, these meters offer an easy, low-cost setup and require little maintenance.   Units provide standard accuracy and may not withstand caustic media.  Units can be a visual indication only or with pulse or analog outputs.
