U1000MKII-FM Fixed Clamp-on, Ultrasonic Flow Meter
The ULTRAFLO U1000MKII-FM is a fixed, pipe-mounted ultrasonic flow meter designed for non-invasive flow measurement on pipes from 22 mm to 180 mm outside diameter. Its clamp-on installation avoids cutting into pipework, helping to reduce installation time, system downtime and servicing disruption.
Description
Key features and benefits:
Two adjustable pipe-size options covering 22–115 mm and 125–180 mm outside diameter.
Cross-correlation transit-time ultrasonic measurement for clean liquids.
1 MHz transducers designed to transmit through older, thicker-walled pipes and larger pipework.
Suitable for water and water/glycol applications.
Straightforward clamp-on installation: connect the power, enter the pipe dimensions, position the sensors and secure the meter to the pipe.
Non-invasive installation and dry servicing help to minimise downtime and maintain system availability.
Backlit LCD provides installation and servicing information.
Integrated pulse output, with optional 4–20 mA, Modbus RTU/RS485 and M-Bus communications for connection to energy-monitoring and building-management systems.
