Water & Wastewater Instrumentation

Products › Solutions › Water & Wastewater

Water and wastewater plants move large volumes that are often dirty, conductive, and carried in part-full pipes or open channels. Dependable flow, level, and pressure measurement keeps intake, treatment, distribution, and discharge running and compliant. Instranova supplies robust, low-maintenance instruments suited to clean water, raw sewage, and sludge.

Flow

Metering mains, treated effluent, and gravity sewers.

Magnetic Flow Meter
Full-bore, lined, obstruction-free metering of conductive water and effluent; the treatment-plant standard.

Partially Filled Pipe Magnetic Flow Meter
Level plus velocity for gravity sewers and channels that run part-full.

Level

Level in wet wells, reservoirs, tanks, and open channels.

Ultrasonic Level Transmitter
Non-contact level for wet wells, channels, and storage; nothing touches the water.

Radar Level Transmitter
Non-contact radar for tanks and reservoirs, unaffected by vapor, foam, or condensation.

Hydrostatic Level Transmitter
Submersible hydrostatic level for wells, reservoirs, and deep tanks.

Pressure

Pump and pipeline monitoring.

Pressure Transmitters
Pump discharge, network, and filter pressure across the plant.

Temperature

Process temperature in treatment.

RTD Temperature Sensor
Pt100 temperature for digesters, aeration basins, and process water.

Materials and design

Water and wastewater instruments must resist abrasion, fouling, and submersion. Magnetic-meter liners and electrodes are chosen for raw or treated water; submersible sensors are sealed to IP68; and non-contact level avoids contact with screenings and grease. Hazardous areas such as digesters and pump stations may require intrinsically safe (Ex ia) versions. Confirm wetted materials and ratings for your service at the time of order.

Application examples

Measuring instruments are used across the plant:

Intake and raw water: flow and level
Pump and lift stations: wet-well level, flow, and pump pressure
Treatment basins and clarifiers: level and flow
Digesters and aeration: temperature, level, and flow
Effluent and discharge: flow, including part-full, for compliance reporting
