Moisture meter (in oil)

OM-11 series
Insert the electrode in a pipe and you can measure moisture content continuously

Flow oil in a electrode in coaxial cylinder, and measure change of capacitance to detect water content. The meter calibrate for each oil type so it guarantee high precision and stability. Typical oils (heavy oil, lubrication oil, etc.) are already register their spans so you just adjust only zero point to use the meter.

  • For liquid

Features, keys

  1. The electrode is simple in design and it does not have much pressure loss, making for a long service life
  2. A highly sensitive and high precision capacitance-measuring device is used for the converter so the meter detects water content stably
  3. As the meter has a temperature correction function, there is no measuring error even when the oil temperature changes
  4. The controller allows registration of the oil type, so it can measure water content in various types of oil
  5. Quick zero and span adjustments

OM-11 configuration diagram


If this moisture meter is used together with a water remover in oil, you can measure the moisture level more precisely by adding a zero adjustment signal right after the water is removed.
