Pipe Flow Meters: Insertion Turbine Flowmeters are the ideal flow meter for large pipes

This innovative, robust insertion turbine flow meter combines proven technology with modern materials and design and is the ideal flow meter for large pipes. The PVDF turbine rotates freely on a 316 St St shaft and has specially aerofoil shaped blades to extend the dynamic range of the meter. The specially contoured housing further improves the meters linearity particularly at lower fluid velocities. Each insertion flow meter contains two sensors, one self powered for our battery operated equipment and the other an open collector transistor.

A reed switch may be specified for hazardous areas where simple apparatus is acceptable. The insertion flow meter body is manufactured from AISI316 stainless steel and as standard is supplied with 1.5M of five core screened instrument cable. The Metra-Count, Metra-Smart and Metra-Batch devices can all be mounted directly onto the insertion flow meter (via a mounting stalk) and all of these can be self powered with the exception of Metra-Batch which requires an external power source.

Flow Meters for Large 40 –900mm Pipes

These insertion turbines provide a cost effective and simple means to measure the flow of a wide range of low viscosity liquids. Installation is quick and inexpensive in pipes from 40 mm diameter up to 900 mm diameter. For rate and total applications a self powered instrument can be mounted directly onto the meter for a standalone measurement. Other instruments permit high and low flow alarms, 4-20 mA loops or even batching functions, these all require external power. The meter requires at least ten pipe diameters of straight pipe upstream and five downstream to ensure a fully developed flow profile and accurate measurements. Large disturbances may require greater straight lengths.
