InnovaSonic 203 Economical Ultrasonic Transit-Time Flow Meter
Ultrasonic Liquid Flow Meters
Sierra’s new InnovaSonic® 203 ultrasonic flow meter delivers highly accurate and repeatable flow measurement for water at a significantly reduced cost. Incorporating the core technologies of Sierra’s flagship 205i, the design of the 203 universal transit-time flow meter is focused on those features that optimize the measurement of water flows in HVAC, irrigation, and other water applications.
Ideal for pipes up to 48” (1200 mm) in diameter, the 203 promises accuracy to +/-1.0% of reading, repeatability of +/-0.3% of reading and a temperature range of 32°F to 140°F (0°C to 60°C).
The 203 offers low power consumption and high reliability at a very competitive price. An easy to read display and clear, user-friendly menu selections make using the instrument simple and convenient. It can be configured via a 4x4 keypad and features a 20 x 2 digit alpha-numeric display without any additional programming devices.
The 203 features a programmable frequency output, a relay output and a programmable current loop output. RS 232 and MODBUS RTU is standard. RS 485 is optional.
The InnovaSonic® 203 is packaged in a lightweight polycarbonate IP65 housing and includes clamp-on encapsulated IP 68 sensors that are easy to install and require no cutting, thereby reducing installation and labor costs.
