The sensor 8030 HT has been designed to measure the flow rate of
neutral or slightly aggressive solid-free liquids.
There will be no manufacturer warranty for damages caused by
unexpected handling or wrong usage of the device. The warranty on the
device becomes invalid if any modification or change is made on the
device.

- Always ensure the materials in contact with the medium to measure are
chemically compatible with this medium.
- To clean the device, only use chemically compatible products.
- Always protect the device from electromagnetic perturbations,
ultraviolet radiations and, when installed outside, from the effects of
climatic conditions.
EMC: EN 50081-1, 61000-6-2
Security: EN 61010-1
Vibration: EN 60068-2-6

The flow sensor 8030 HT is built up with an electronic module SE30 HT
associated to a fitting S030 HT with integrated metallic paddle-wheel.
The sensor detects the rotation of the paddle-wheel which produces a
signal whose frequency f is proportional to the flow rate Q.
Two electronic module versions with frequency output are available:
- either with 2 pulse outputs (transistor NPN and PNP), where f = K.Q
- or with one sinusoidal output (coil), where f = 2 K.Q
where f = frequency in Hz
K = K factor specific to each fitting in pulses/l,
Q = flow rate in l/s
The electrical connection is carried out via an EN 175301-803
connector.
