The product uses a high-performance pressure sensor as a sensing element, which could measure liquid static pressure that is positively proportional to level depth precisely, and transform pressure signal into standard current/voltage signal output by amplifier circuit to measure accurate level depth. The product has high accuracy, compact size, easy installation, can be submersible into the liquid directly to measure level from transmitter bottom to the liquid surface. It can be  widely used for water and level measure and control of petroleum, chemi- industry, power station, city water supply and drainage and hydrology, etc

  1. Please be sure the measured media is compatible with contacting material; please pay attention to media density in the measurement (except water);
  2. We provide two kinds of cable, PVC or polyurethane cable. Polyurethane cable is more flexible and If the use has no special requirement, we provide PVC cable as default;
  3. If the product is installed in the “lightning and thunder” area, please note “lightning-proof” in the order. We suggest increasing the Lightning-proof Protection Device to protect the transmitter. Please be sure good grounding as well;
  4. If the user has a special requirement, please feel free to contact our
