Principle of operation

Swimming against the stream requires greater physical strength than swimming with the stream. This 

is the simple fact on which ultrasonic flow measurement according to the phase difference process is 

based. Two sensors positioned opposite one another send and receive ultrasonic signals in alternation. 

When static media are used, both sensors receive the sent ultrasonic signal in phase, meaning without 

phase difference. If flowing media are used, there is a phase shift. The phase shift is different when 

measured in the direction of current than when measured against the direction of current. The phase 

difference is directly proportional to the speed of the flow. The flow volume is determined from the 

speed of the flow and the known diameter of the pipeline.

Safety notes

• 

Read the instruction manual before commissioning.

• 

Connection, mounting, and setting only to be done by trained specialists.

• 

The Flowcont UN is not a safety module according to the EU Machinery Directive.

• 

Observe the national safety and work safety regulations.

• 

Repairs may only be carried out by the manufacturer. Changing or altering the device is not 

permitted.

• 

Wiring work and opening and closing of electrical connections are only to be carried out in a de-

energized state.

• 

Incorrect handling or improper use can lead to malfunctions in your application.

• 

Flowcont UN can be used by the Pressure Equipment Directive (PED) of group 2 only for „non-

hazardous liquids.“

Applications

The Flowcont UN flow meter is particularly suited for measuring highly dynamic processes in pipelines. 

The device measures liquids. It can be used in the following applications, to name but a few:

• 

Chemical supply for controlling, logistics and monitoring

• 

Filling processes in the food industry

• 

Production machines for controlling and monitoring formulae

• 

Valve control for dosing liquid volumes

• 

DI water supply

• 

Dynamic processes

The following featured comprise its performance characteristics:

• 

no moving parts, and thus no wear

• 

high reproducibility

• 

ease of cleaning

• 

tamper-proof

• 

compact design

• 

integrated empty pipe detection

• 

chemical resistance

• 

integrated display with membrane keyboard
