Paddle wheel flow meters belong to the category of insertion type flow meters. The rotating paddle wheel generates a signal in proportion to the velocity of the moving fluid which is read in terms of the flaw rate. Because the pipe's cross-sectional area is known and remains fixed the average velocity is an indication of the flow rate.
MATERIAL OF CONSTRUCTION

All installation fittings are supplied along with the flow sensor. The sensor may be installed in a PP wafer drilled asper BS10 TABLE E OR ANSI B16.5 standards or a Glue-on PVC saddle or a SS stub welded to a MS/SS plate.
ADD-ON FEATURES *
- 230vac, 1a (Resistive load only) max. with 1NO and 1NC contact. 1 or 2 Relay outputs can be given for giving a signal based on flow rate or total flow or both depending upon the requirements.
- Customer to clearly specify the number of relay outputs required and also whether the cut-off signal is to be based on rate of floe or total flow.
INTERFACING WITH PLC
An open collector pulse output or a 4-20mA signal can be provided for interfacing with a PLC or connecting to Recorders.
Programmable pulsed output available
THE DOWNTIME ELIMINATOR WET TAP VALVE ASSEMBLY
You can completely eliminate downtime resulting from flow sensor maintenance, with the simple addition of the Wet Tap Valve assembly. Should a sensor, rotor, or O-ring need to be replaced, the wet tap assembly provides a safe and fast method of removing a specially extended sensor from your pipe without system shut-down.
