Case Study – Sewer Monitoring
Background
The business of sewage monitoring in sewers is
accelerating across many countries. Strict regulations,
the need to avoid environmental disasters, violation
fines, early warnings and planning needs are just some
of the forces shaping this growing trend.
Challenges
Quantifying sewage flow and level is one of the most
challenging engineering tasks for the instrumentation
industry:
• Measured fluid is extremely hostile. Fluid is
turbulent, uneven, filled with solids of various
types, exhibits foam, varying temperatures and
chemically aggressive.
• Sewers are isolated and crowded. No power. No
data cables. Narrow manhole.
Solution
GaugerGSM is a remote level monitoring platform. With
dedicated firmware and accessories, the platform
becomes a powerful customized solution. Sewer
monitoring highlights:
• Level measurement based on ultrasonic technology.
No contact is made with the fluid. No moving parts.
Structure is robust and long lasting. Sensor is made
of chemically resistant PVDF. System is hermetically
enclosed and rated IP68.
• Battery based operation. An external 4-cell pack can
operate for 2 years before replacement. Operation
is based on a programmable switch accessory for
ultra low power mode.
• Cellular based communications. A GSM modem is
embedded within the sensor to create an extremely
compact solution. The internal GSM antenna is not
exposed and allows communication from within
deep sewers. This communication infrastructure is
always present and available.
