AW-Lake’s Water Inline Ultrasonic Flow Meter was designed to accurately measure the flow of water and water glycol solutions in small pipes from ½” – 2½” in diameter. The no-moving-parts design operates over a wide flow range with excellent low flow accuracy. The low-cost design is provided with threaded process connections, a 4-20mA analog output and a scaled dry contact pulse output for totalization, as well as Modbus RTU. Units are available with and without a detachable LCD display, which can be mounted up to 5 feet away from the flow meter body for convenience.
• Reliable No-Moving-Parts Design for Long Term Reliability
• High Accuracy Over a Wide Flow Range: ±1% of Reading over Normal Range (25:1), ±2% of Reading over Extended Range (100:1)
• User-Friendly Backlit Display and User Interface
• Detachable Display for Remote Mount Installation up to 5 Feet from the Sensor Body
• Built-In Interval Data Logger for Easy Data Access via Modbus
• ANSI/NSF 61 & 372 Approval
Reliable No-Moving-Parts Design
The Water Inline Ultrasonic meter incorporates a pair of wetted ultrasonic transducers that face each other directly in the flow tube. This configuration maximizes signal strength and
Highly Accurate Over a Wide Flow Range
The flow tube design and direct beam path configuration is optimized for water and water/glycol solutions. This allows for improved accuracy at low flows.
Industrial Automation Protocol
The LCD Display version comes standard with Modbus RTU communications for instantaneous flow rate, volume total, run hours, and diagnostic information.
Easy to Install in Limited Straight Runs
The Water Inline Ultrasonic meter has an innovative flow tube design that simplifies installation by allowing for limited straight pipe upstream and downstream of the meter in most installations.
Simplified Installation and Commissioning
Each Water Inline Ultrasonic meter is fully configured and programmed before it leaves the factory and is ready for use upon delivery.
Safe in Wet Locations
IP67 (NEMA 6) rating allows for safe operation during temporary periods of submergence.
±1.0% of reading over 25:1 turndown
±2.0% of reading over 100:1 turndown
