Ruby bearings and a non-drag pick-off give these adjustable insertion flow sensors the widest flow range of any of the paddlewheel types. A sensor detects the passage of miniature magnets in the six rotor blades. The resulting squarewave signal can be sent for hundreds of feet without a transmitter, over unshielded cable. This signal can be connected directly to many PLC's and other controls without any additional electronics. Installation fittings are standard 1- 1/2" or 2" NPT. A depth adjustment system allows two basic sizes to cover pipe sizes from 3" to 48".
A modular system of electronics can be attached directly to the flow sensor or remotely mounted. The FT415/420 provides full indication of rate and total, plus 4-20 mA output. The AO55 provides a 4-20 mA output, and the PD10 has a programmable pulse output for pump pacing.
The installation fitting of the EX sensor is standard male NPT, and can be directly threaded into ordinary saddles or threaded weld fittings. The IP115 and 215 include an isolation valve, allowing hot-tap installation, or installation and removal under pressure. The standard isolation valve is Bronze, but a 316 Stainless Steel valve is available as an option if needed.
