Simple to install with time-honored reliable
performance, Signet 515 Rotor-X Paddlewheel Flow
Sensors are highly repeatable, rugged sensors that
offer exceptional value with little or no maintenance.
The output signal of the Model 515 is a sinusoidal
frequency capable of driving a self-powered flowmeter
(Model 3-5090). The wide dynamic flow range of 0.3 to
6 m/s (1 to 20 ft/s) allows the sensor to measure liquid
flow rates in full pipes and can be used in low pressure

systems.

The Model 515 sensors are offered in a variety of
materials for a wide range of pipe sizes and insertion
configurations. The many material choices including
PP and PVDF make this model highly versatile and
chemically compatible to many liquid process solutions.
Sensors can be installed in up to DN900 (36 in.) pipes
using Signet’s comprehensive line of custom fittings.
These custom fittings, which include tees, saddles, and
weldolets, seat the sensor to the proper insertion depth
into the process flow. The sensors are also offered in
configurations for wet-tap installation requirements.
