Turbine flow transmitter RT-0 series

high-precisionanalog output

A turbine acts as the primary sensor; its rotational speed is proportional to the flow rate. The rotational speed is detected by means of pre-tensioned Hall sensors, i.e. there are no magnets in the flow space. The LABO-RT electronics make various output signals available: ●Analog signal 0/4..20 mA (LABO-RT-I) ●Analog signal 0/2..10 V (LABO-RT-U) ●Frequency signal (LABO-RT-F) or ●Value signal pulse / x litres (LABO-RT-C) A model with switching output is also available (see separate datasheet). If desired, the range end value can be set to the currently existing flow using "teaching". Handling and operation Installation As with all flow meters, if possible the turbine should be installed ahead of a valve (on the pressure side). Good degassing should be ensured. 10 x D calming sections are recommended before and after the turbine in order to maintain the specified accuracies. The turbine should be filled with fluid at all times. The electronics housing does not project into the flow space.
