Water & Wastewater Solutions

United Electric Controls is the leader in safety, alarm and shutdown processes. The UE line of pressure and temperature switches and transmitters meet the application challenges of water and wastewater treatment. They provide precise pump control, handle slurry service, submersible pressure monitoring, and stand up to corrosive media and atmospheres. Included in UE's offering is the innovative solid state One Series that is the ideal solution for isolation ring monitoring, providing a switch, digital read-out and 4-20 mA signal in one cost-effective instrument.  For further information read our Water & Wastewater Overview.

FILTER MAINTENANCE

 

Filtration is a key operating function of any water & wastewater plant. UE offers a versatile selection of pressure and differential pressure switches for the challenges associated with plugging of spray nozzles; fouling of pipes; blinding of scrubbers, membranes, R/O and analyzers; wearing of pump gland seals; plugging of irrigation heads; or initiating an automatic backwash cycle.

 APPLICATIONS:

  • Digesters
  • Septic centrigure feeds
  • Wastewater transporting
  • Thermal recovery
  • Effluent monitoring
  • Well and basin overflow
  • Sewage lift stations
  • Chemical feed pumps
  • Pressure reducing valves
  • Wastewater recovery
  • Isolation ring pressure sensing
  • Monitoring lubrication oil
  • Chemical injection
  • SCADA system alarm and data input
  • Distribution and storage
  • Pump stations for hydrogen sulfide
  • Tank levels
  • Membrane filtration

CORROSION - RESISTANT SOLUTIONS

 

Harsh environments and corrosive media require corrosion-resistant protection, so UE switches & transmitters incorporate 316 stainless steel enclosures and wetted material. 12 Series pressure switches provide a rugged, compact solution where instantaneous switching is required - i.e., valve actuation. UE's smart TX200H pressure transmitter monitors chemical treatment and other processes using the 4-20 mA output while transmitting process variable, tag and realtime diagnostic information to a control room using HART® 7 communication protocol.

APPLICATIONS:

  • Digesters
  • Septic centrigure feeds
  • Wastewater transporting
  • Thermal recovery
  • Effluent monitoring
  • Well and basin overflow
  • Sewage lift stations
  • Chemical feed pumps
  • Pressure reducing valves

PUMP CONTROL

 

For reliable, repeatable and accurate pump sequencing, you cannot make a better choice than UE's solid-state One Series switch models. These electronic monitors feature up to two fully programmable set points and deadbands that cover the entire range of the sensor. Modifying these settings is easy, yet remains tamper-resistant. Use the One Series to precisely control pumps while extending life and preventing cavitation. Sensor materials are all 316 stainless steel with welded diaphragms for gage and differential pressure.

Three instruments in one: Switch | Gauge | Transmitter

APPLICATIONS:

  • Reduces costs/increases reliability
  • A single pressure port to reduce potential leaks
  • Digital display, switch and 4-20 mA output
  • Self-checking diagnostics
  • 0.1% of range repeatability
  • Simple keypad setup and checking

 

REVERSE OSMOSIS SYSTEMS

 

Mineral deposits inside and outside boiler tubes result in inefficiencies causing poor steam production and lack of power produced at the turbine. Avoid costly delays and maintenance by monitoring and trending your reverse osmosis system with reliable and accurate sensing solutions. Automate cartridge replacement with a wide variety of pressure and temperature sensors and reliable switch solutions. The UE line protects pumps and equipment throughout the facility.

Provides the perfect control of pump operation & sequencing! Using UE's Solid State One Series:

APPLICATIONS:

  • Fully adjustable on/off start/stop over the full sensor range via front keypad
  • Tune pump to precisely match operating sequence and tank levels
  • Extend pump life and protect from cavitation
  • 316 stainless steel sensors with wide selection of differential and gage pressure ranges
