DN125,DN150,DN200,DN250,DN300,DN350,DN400
1. Application
Could be used in many fields for high solids concentration monitoring, such as in sewage treatment, sludge processing, beneficiation, coal washing, metallurgy, paper making process and so on.
• Water supply plants and sewage treatment plants
Sludge from return cannel, primary sedimentation tanks, secondary sedimentation tank, thickening tank, or sludge before dewatered.
• Coal preparation plant, Mining, Pulp & Paper, power plant
Slurry concentration, Slime concentration, Mortar concentration, Pulp concentration
2. Features and Benefits
• Based on the principle of reflected ultrasound, no ray contamination and is absolutely safe.
• The ultrasonic energy emission is automatically adjustable,work on a variety of medium and wide measurement range.
• Advanced circuit design and software algorithms keep the analyzer from environmental interference.
• The immersion mounting sensor is designed for Pools, rivers, and large diameter pipes; the flange mounting sensor for pipes with fluid; the insertion mounting sensor for large-diameter pipes or tanks.
• Large LCD screen displays the measurement data and the trend curve.
• % or g/L is optional for measurement unit,.
• Onsite calibration, user-friendly
• Isolated 4~20mA output, upper and lower limit alarm
