InnovaSonic 203 Clamp-On Ultrasonic Water Flow Meter

InnovaSonic 2013 Ultrasonic Water Flowmeter by Sierra InstrumentsUltrasonic Flowmeter for Accurate Results

The InnovaSonic® 203 liquid flow meter from Sierra Instruments has been optimised for customers who are looking for high performance, but need a lower-cost, less feature-rich option for dedicated clamp-on ultrasonic metering. The 203 digital liquid flow meter optimises the measurement of water as it flows in HVAC, irrigation and other liquid applications.

  • High performance at an affordable price
  • Simply clamp-on outside of pipe for easy set up
  • Save time with no pipe cutting or process shutdown
  • For fast delivery, buy online, next-day shipment
  • Flexible rent or Rent-2-Own programs

This economical ultrasonic liquid flow meter delivers a highly accurate and repeatable flow measurement for liquids at an economical price. It is ideal for pipes up to 1200mm (48 inches) in diameter. The 203 promises accuracy to +/-1.0% of reading, repeatability of +/-0.3% of reading and a temperature range of 0°C to 60°C. Another added feature is the 203 offers lower power consumption while keeping high reliability at a very competitive price.

The easy to read display and dual-function quick keys make setup quick and simple. The 203 also features a programmable frequency output, a relay output and a programmable current loop output. RS-485 and Modbus RTU are standard.

The InnovaSonic 203 is packaged in a lightweight polycarbonate IP 65 housing and includes clamp-on encapsulated IP 68 sensors that are easy to install and require no pipe cutting, reducing installation and labor costs.
