Flow Sensors
Paddle Type Insertion Flow Sensors with Hall Effect Output
Model: PE 9900
Hall Effect Flow Sensors for Liquid Flow Measurement
Liquid passing through the valve turns a rotor. A hall effect sensor converts the rotor speed into a pulse signal, giving the flow rate. Available in PP and SS valves, including flameproof versions.

How to Choose a Flow Sensor
Use these six steps to specify the right paddle type flow sensor.
1. Check your fluid
Clean, non-abrasive liquid with up to 1% solids, non-magnetic and below 100 micron.
2. Note pressure and temperature
PP valve: 6 bar and 60°C. SS valve: up to 10 bar and 100°C.
3. Pick the valve material
PP or SS, in magnetic or non-magnetic versions, to suit your fluid and temperature.
4. Decide on flameproof
Choose the SS flameproof version where flameproof equipment is required.
5. Match the signal
12 to 24 VDC supply with a 30 to 70 Hz pulse output for your indicator or controller.
6. Select the fitting
T type or weld-on adapter, fitted to your pipeline for best performance.
