Global Water’s WL430 Sewage Lift Station Level Sensor is ideal for measuring level in high solids environments

It is based on over 30 years of design and field service experience. The WL430 has a standard 4-20 mA output for interface with most datalogging and remote monitoring equipment. “Steel Cage” Design The WL430 consists of a submersible pressure sensing element encased in a 316L stainless steel housing. The unit’s “steel cage” design offers the highest reliability in level measurement for severe high solids environments such as sewage, lift stations, storm canals, wet wells, and slurry tanks. The ”steel cage” gives full protection and allows sensing of sewage levels no matter how much debris, mud, or sand builds up.

Barometric Pressure Compensation

The WL430 includes 40 ft of polyurethane shielded and vented cable, and additional cable lengths are available up to 500 ft. The instrument’s unique vented cable system allows for barometric pressure differential compensation (described further on page 6),while the unit is protected from the elements with a Gortex filter encapsulated tip.

Lightning Strike Protection

The WL430 includes an exclusive lifetime warranty against lightning strikes. The sensor’s electronics are capable of withstanding lightning strikes and meet RCTA/DO 160D for lightning direct effects and surge protection for FAA and MIL-STD test and NASA standard electrical surge requirements. The WL430 is also CSA explosion proof and intrinsically safe if used with a client supplied barrier strip.
