Applications

Channel Networks - Pump Stations and Lifting Facilities

Flow Rate Monitoring on Pumps

Application

Cast iron pipe DN 200
Full filled
Old existing line (condition unknown), installed pipe system cannot be modified

Definition of tasks

Flow rate monitoring of feed pump to detect clogging and dry run
Tendency monitoring of feed pump to detect wear and tear
Optimisation of repair and maintenance intervals
No high accuracy required (permissible error higher than 10 %)
Good reproducibility

Principle of contactless Flow Rate Monitoring

Solution

A clamp-on) Doppler sensor Type NivuGuard 2 was used.
The sensor provides a flow-proportional 4-20 mA signal as well as a digital error message signal directly to the telecontrol substation installed on site.

Advantages

Direct connection to the PLC available on site (no transmitter required)
No modification of old pipeline necessary
