Products Description
The light waves sent by the sludge concentration meter through the sensor transmitter are absorbed, reflected, and scattered by the measured object during transmission, and only a small part of the light can shine on the receiver. The transmittance of the transmitted light is proportional to the concentration of the measured sewage. The concentration of the sewage is calculated by measuring the transmittance of the transmitted light. Applied in water plants (sedimentation tanks), paper mills (pulp concentration), coal washing plants (sedimentation tanks), power plants (slurry sedimentation tanks), sewage treatment plants (inlet and outlet, aeration tank, reflux sludge, primary sedimentation tank, secondary sedimentation tank, concentration tank, sludge dewatering), etc.
Features
- Multi beam RD measurement technology to compensate for the effects of ambient light, dirt, and component aging
- Multi point calibration ensures accuracy over a wide measurement range
- Output of various variables such as current and relays, intelligent control of the system
- The sensor can be configured with an air blowing device, which is controlled by the transmitter for self-cleaning
- Multiple installation methods such as immersion and pipeline insertion
