FarSight Non-contacting Velocity Measurement

 

With excellent low velocity measurement capabilities, enhanced beam-width, built-in tilt compensation, rainfall interference discrimination, and low-power consumption with Modbus output, the Pulsar Measurement FarSight is the right choice for demanding remote or mains-powered velocity applications. 

 

Specifically designed with global challenging weather conditions in mind, the FarSight velocity sensor has been tried and tested in a wide range of climate conditions, including UK tropical storms Dudley, Eunice, and Franklin. With no loss of data recorded, the FarSight provided repeatable and accurate results thanks to its more powerful signal processing and rainfall discrimination system. 

 

Skill and resource requirement from installation is minimized thanks to the built-in tilt sensor which auto-mitigates user error in installation angle. With the standard Modbus output, the FarSight is compatible with both third-party RTU's or Loggers as well as controllers from Pulsar Measurement like the FlowCERT and The Ultimate Controller. The FarSight can be used with continuous power, or at longer intervals to reduce power consumption when connected to a logger. 

The FarSight can be mounted as far away as 15 meters (49 feet) from the water surface, making it great for applications where the mounting location can't be changed, like river flows underneath a bridge. The measurement area of the sensor can be as large as 3 meters (9.8 feet), which means less sensors are required for measuring the velocity across wider channels. The FarSight is the right choice for applications with variable flow rates thanks to the ability to measure velocities as low as 0.2 meters per second (0.66 ft/s).
