| 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. |
