Non-contact Surface Velocity sensor. Directly connect to any monitor that accepts serial inputs. Low power and easy to use. Compatible with all Blue Siren monitors with an X-Port. The Stalker sensor is a great Non-contact Velocity sensor for monitoring large open channels and sewer pipes where installation of wet sensors poses a safety concern. Simply point the sensor at the flow stream and be ready in minutes to monitor how fast the velocity of the water. Great for large open channels, rivers, streams and tidal inflow.
