Main design features

When the two-wire-loop-powered sensor is connected in series with a DC power supply, the MD 126 generates a 4 to 20 mA output signal proportional to the level of the liquid.

The output signal can be connected to the mA–input of set point relays, chart recorders, indicating instruments, PLC, pump-controls, etc. The number of devices in series and the length of the cable from the sensor to the devices depend on the supply voltage.

The ceramic sensing element can withstand very high overpressure without damage.

Applications
  • The commercial wastewater market
    Commercial waste disposal from toilets
    Commercial wastewater from toilets comprises all sewage water flushed from toilets on commercial, industrial or public properties.
  • The commercial wastewater market
    Commercial wastewater without toilet waste
    Commercial wastewater without toilet waste includes drainage and grey wastewater.
  • Lifting stations, submersible pumps and control system in a house showing Sulzer products for domestic wasterwater with toilet waste
    Domestic waste disposal from toilets
    Domestic wastewater from toilets comprises all sewage water flushed from toilets or residential properties.
  • Lifting stations, submersible pumps and control system in a house showing Sulzer products for domestic wasterwater without toilet waste
    Domestic wastewater without toilet waste
    Domestic wastewater without toilet waste includes drainage and gray wastewater.
  • Wastewater collection process network - pumping stations
    Network pumping station
    Network pumping stations collect municipal wastewater from residential homes and communal schemes. Installed in dry or wet wells, the pumps deliver the effluent to a terminal pumping station. Since most pumping stations are not equipped with screens, the pumps must cope with difficult materials such as fibrous sanitary and packaging items.
  • Pressurized systems
    Pressurized sewage systems are well suited to outlying locations such as holiday areas and coastal regions, where there may be no direct access to local gravity-based systems. They can also provide an economical alternative to gravity sewers, since they involve smaller pipeline diameters and less excavation.
  • Control panels type ABS CP 116 and CP 216
    Pumping station control
    Control systems provide functionality and data that can be used to improve the availability of pumps, pumping stations and entire collection networks. They are a simple way to reduce not only the risk of downtime and flooding, but also maintenance and energy costs. Sulzer has a full range of control systems that are as easy to use as they are sophisticated.
  • Wastewater collection process network - storm water pumping stations
    Storm water pumping station
    During heavy rainfall, storm water pumping stations deliver large volumes of water at low head to receiving surface waters or sewers. Having long been a part of flood management, they are increasingly involved in climate adaptation strategies for low-lying coastal cities.
  • Wastewater collection process network - terminal pumping stations
    Terminal pumping station
    Terminal pumping stations receive municipal wastewater from network pumping stations. Installed in dry or wet wells, the pumps forward the medium to a treatment plant for final purification. Due to the lack of screens at most pumping stations, difficult materials such as fibrous sanitary and packaging items are a constant threat to uptime.
