HVAC flowmeters

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.
