Tidalflux measures the flow of partially filled pipes

The Tidalflux mag meter from Krohne can measure the flow of partially filled pipes to combat inflow and infiltration, storm surges and surcharges.

Tidalflux mag meter

This is the Tidalflux which is built to measure flow in partially filled pipes. It is a magnetic meter and operates off the laws of induction. The electrodes have been moved to just below 10% of level of the pipe.

Right now it is being applied in combined sewer overflow and sanitary sewer overflow applications due to the variability in flow range. It is a closed pipe measurement that requires no special piping. It also protects from inflow and infiltration and surcharging.

The Waterflux uses a specially designed throat for accurate measurement and can be upgraded to include temperature and pressure sensors.

This is the Waterflux. It has a unique metering design for accurate measurement.

The throat design of the Waterflux doubles the velocity of the flow through the meter, which Krohne says cleans up the flow data similar to a flow conditioner.

It comes in sizes up to 24 inches, and pressure and temperature can be built in. It is IP 68 and NSF 61 approved.

The throat design doubles the velocity through the meter and cleans up the flow profile for a clean signal. This is what leads to the zero up and zero down measurement. It's almost like a built in flow conditioner.

The company has a global footprint with manufacturing in UK, US, Germany, France and Holland.
