|
| The hydrotechnik RE4 flow measuring turbine is a flow rate meter. The turbine blade wheel is axially driven by the flow stream, rotating in proportion to the mean flow velocity. A non-contacting inductive pick-up generates a pulse each time its' electromagnetic field is interrupted by the rotating blades of the turbine. These pulses are then directly conver-ted into a flow measurement by the associated electronic instrumentation, in for example l/min. An advantage of the RE flow meas-uring turbine are the integrated test points which enable additional measurements of pressure and temperature. |
