104 LOH Loss of Head Transmitter

It measures Loss of Head (LOH) in the gravity filter beds of Water Filtration plants or Traveling water screens in raw water treatment plants. Loss of head is measured by monitoring the level in High Pressure and low pressure side of the gravity filter/traveling water screen and showing the difference in these two levels.
