Hach, EM950.0100, FH950 Portable Velocity Sensor, 100' Cable

The sensor to the perfect handheld solution for wastewater and environmental flow monitoring.
The EM950 electromagnetic velocity and depth sensor has no moving parts and never requires maintenance, making it one of the lowest maintenance solutions on the market. Turbulent, noisy and low velocities are easily metered. When the sensor is placed in flowing water, its magnetic field creates a voltage that is sensed by electrodes embedded in the sensor. The voltage amplitude, proportional to the water velocity flowing around the sensor, is electronically processed by the smart sensor's microprocessor and is digitally transmitted through the cable to the portable meter display. Portable FH950 meter sold separately.
Maintenance-free electromagnetic sensor
Available with either Velocity or Velocity and Level capabilities, the EM950 electromagnetic sensor has no moving parts and never requires mechanical maintenance, making it one of the lowest maintenance solutions on the market.
Accurate even in difficult monitoring sites with smart sensor capabilities
With an innovative and compact sensor shape with intelligently-designed flow characteristics, the EM950 sensor delivers reliable measurements at low velocities, in very shallow water, and in turbulent flow conditions. It even takes accurate readings in sediment, weed or organic debris-choked water. Plus, with an optional pressure cell for automatic level measurement and sensor positioning, the Hach EM950 sensor with FH950 hand-held meter is known for having as much brain as it has brawn.
