EM950 Velocity Sensor

For enhanced functionality, the sensor can be equipped with an optional pressure cell for automatic level measurement and precise sensor positioning, further increasing its versatility and accuracy. When the sensor is placed in flowing water, it generates a magnetic field that creates a voltage detected by electrodes embedded within the sensor. The voltage, which is proportional to the water velocity surrounding the sensor, is processed by the smart sensor’s microprocessor and digitally transmitted through the cable to a portable meter display, such as the FH950, which is sold separately.

Available in two versions—one that measures velocity only, and another that measures both velocity and level—the EM950 sensor is a robust solution for a wide range of applications.

• Maintenance-free electromagnetic sensor
• Accurate even in difficult monitoring sites with smart sensor capabilities
• Effortless Design
• Minimum Sensor Fouling

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

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.

Compact and ergonomically shaped, making it easier to install in tight spaces and less prone to clogging or buildup

The sensor maintains its accuracy and reliability, especially in environments with challenging flow conditions, such as wastewater or industrial processes.
