Submersible pressure sensor type ABS MD 126

Robust and resistant when you need accuracy

The MD 126 is a high-accuracy submersible hydrostatic level sensor. Encapsulated in stainless steel and resistant to sewage water, it is designed to measure levels in liquids such as storm water and wastewater in sump pumps.

Submersible pressure sensor type ABS MD 126
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
  • Commercial waste disposal from toilets
    Commercial wastewater from toilets comprises all sewage water flushed from toilets on commercial, industrial or public properties.

  • Commercial wastewater without toilet waste
    Commercial wastewater without toilet waste includes drainage and grey wastewater.

  • Domestic waste disposal from toilets
    Domestic wastewater from toilets comprises all sewage water flushed from toilets or residential properties.

  • Domestic wastewater without toilet waste
    Domestic wastewater without toilet waste includes drainage and gray wastewater.

  • 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.

  • 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.

  • 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.

  • 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.
