220V Digital Suspended Solids Meter For Sewage Treatment
Brief Introduction
- Suspended solids refer to small solid particles which remain in suspension in water. It is used as one indicator of water quality, typically for wastewater applications.
- DUC series suspended solids meter is a digital universal controller for measuring suspended solids (sludge concentration). It is a single parameter controller. The suspended solids (sludge concentration) meter can simultaneously meet the needs of users for detection, control, and remote data transmission, with rich output settings.
- The DUC2-SS is a universal controller specially designed for the DRFN digital series of suspended solids (sludge concentration) sensors and is compatible with all digital suspended solids (sludge concentration) sensors of DRFN.
- Through the DUC2-SS series general-purpose controller, users can query related information such as the working status and the serial number of the connected sensor.
- The instrument has 2 SPST multifunctional relays that can be set and 2 high-precision 0/4~20mA current outputs.

Advantages Of The Suspended Solids Meter
- The suspended solids controller is equipped with RS485 Mudbus RTU, RS485 allows multiple devices to be connected to the same bus for data transmission and control through serial communication protocols, making the integration between devices simpler and more flexible. RS485 uses differential signal transmission, which can resist electromagnetic interference in industrial environments and ensure stable data transmission.RS485 can support relatively long communication distances, allowing devices to be distributed in distant locations while maintaining reliable communication.
- The DUC suspended solids (sludge concentration) meter has the functions of clock and historical data recording, which can meet the higher management requirements of users for data.
- The DUC2-SS-S-A suspended solids (sludge concentration) analyzer has a 3.2-inch display screen and uses a 128*64 black and white graphic dot matrix LCD liquid crystal display, with reasonable interface settings and simple operation.
- The enclosure protection grade of the SS meter is IP66. This material can effectively isolate the pollution and corrosive gas from the external environment.
Applications Of The Suspended Solids Meter
Industrial wastewater treatment, municipal sewage treatment, river and lake monitoring, and other fields.
