Turbine flow transmitter LABO-RT-C

precisionhigh-precision

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. 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". ● High precision ● No magnetic components in the flow space ● High pressure resistance ● 0..10 V, 4..20 mA , frequency/pulse output, completely configurable 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. Operation and programming The teaching process can be carried out by the user as follows: ● The flow rate to be set is applied to the device. ● Apply an impulse of at least 0.5 seconds and max. 2 seconds duration to pin 2 (e.g. via a bridge to the supply voltage or a pulse from the PLC), in order to accept the measured value. ● When the teaching is complete, pin 2 should be connected to 0 V, so as to prevent unintended programming.
