The FP-5600 and FP8500A series low flow sensors are high resolution, low power devices ideal for measuring flow in piping systems with extremely low velocities. Utilizing insertion paddlewheel technology, these sensors are easy to install and maintain. They incorporate state-of-the-art, advanced Hall-effect design, allowing them to operate with a wide range of voltages and current supplies. The sensors have a wide flow range and reverse polarity protection. The insertion design easily adapts to a wide range of applications.

Can this product be used to measure flow in an open area (without housing)?

Asked by: Amit213
Thank you for your inquiry about the paddle wheel sensor. Unfortunately, our paddle wheel sensors require a fitting to measure the flow rate in a closed pipe, not in an open channel.

We replaced an older FP-5601 (purchased in 2011, serial number 61106270253) with a newer FP-5601 (purchased in 2018, serial number 61504140751). Have the K factor conversions changed over time between these two instruments?

Asked by: davidb
Thank you for your question? The K-Factors of the FP-5601 have not changed over the years. They only change with different pipe sizes.
