Ultrasonic Flow Meters

Flanged ultrasonic flow meters are easy to use thanks to their fixed flange mounting and work on the same principle as inline and portable ultrasonic meters. The sensors are mounted on a stainless steel spool made to the chosen flange size, so no sensor alignment is needed.

Their general features are:

Accuracy better than 0.5 %
Improved software that makes the measurement more stable and raises performance
RS485 serial communication
4–20 mA and 0–10 V analogue output
Able to measure sewage water
Frequency and pulse output
Three sensor types can be used: clamp-on, insertion and inline
All settings can be held in flash memory
More than four communication protocols can be selected: MODBUS, M-Bus and others
Instantaneous and total flow can be stored by month/day and transferred over MODBUS
Fluid density can be selected
Can be powered by battery or an 8–36 V DC supply
