Insertion Turbine Flow Meters
This innovative, robust insertion turbine combines proven technology with modern materials and design. The turbine rotates freely on graphite/PTFE impregnated PEEK™ bearings 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 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 were simple apparatus is acceptable. The body is manufactured from AISI316 stainless steel and as standard is supplied with three meters of five core screened instrument cable. The Metra-count, view, smart and batch can all be mounted directly onto the 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.
Insertion flowmeters measure the point velocity of the liquid in a pipe. Flows in very large pipes can be measured this way using relatively inexpensive metering devices. There are two basic types of insertion turbines, an axial (propeller type) and a radial type (undershot water wheel). Overall accuracy is similar in either case. In both turbine types the fluid velocity profile in the pipe must be “fully developed” as the arithmetic for the whole pipe throughput is derived from this point flow measurement. Upstream disturbances such as control valves, pipe bend, pumps and pressure regulators must be positioned well away from the flow meter insertion point, up to 100 pipe diameters in the worst case. Due to the relatively small disturbance the metering head introduces to the pipe, pressure losses for this type of flowmeter are very low making energy savings by reducing pumping costs. Some types of insertion turbine are self powered permitting their use in remote areas where power is an issue.
