Signet 3-2537-XC-PX Paddlewheel Flow Sensor

What is 2537 Paddlewheel Flow Sensor ?

The Signet 2537 Flow Sensor is the next generation in fluid measurement technology from the inventor of the original paddlewheel flowmeter. This sensor is an enhancement on what is already an industry standard. It has the added functionality of various output options including flow switch, pulse divider, digital (S3L) or 4 to 20 mA. Additionally, it offers low flow, low power and high resolution and can be configured on-site directly through the built-in user interface.
