Ultrasonic Water Flow Sensor, SU Series

The ultrasonic flow meter of the SU series monitors liquid media such as water, glycol solutions or industrial oils. It detects the three process categories volumetric flow quantity, consumed quantity and medium temperature. Peak consumption, present consumption or accumulated consumption can be accessed and adjusted via programmed switch and alarm level settings - all at the touch of a button.
The units feature two switching outputs which can be programmed as normally open or normally closed. For output of the measured value, one switching output can also be configured as a scalable analogue output. For consumed quantity monitoring, the other output transmits counting pulses to the controller.
In addition to volumetric flow monitoring, the SU also monitors the temperature of the medium. It is displayed on the unit and provided for signal processing. The sensor is thus suited for monitoring cooling circuits.

Features and Benefits

• Precise measurement of flow, consumption and medium temperature • For installation in pipes
• With switching output, analogue output and pulse output
• Clearly visible 4-digit LED display
• Can be used for high flow rates
• Measurement of non-conductive water also possible
• With volumetric flow quantity, total quantity and temperature indication

Product Application Information

Suitable for water, oil and glycol solutions.


Threaded (or push-fit) connecting adapters are not included with the volumetric flow sensor. Suitable connectors may be sourced (depending on the type required), for example a G3/4 male to G3/4 female adaptor (RS stock no. 807-766), or similar.
