Intake, treatment, sludge and discharge. A practical application brief for defining a flow measurement system.


Water & Wastewater Flow Monitoring specification sequence: Full-pipe location, Solids & conductivity, Installation checks, Totals & verification

Define the duty


Separate raw water, treated water, chemical feed, sludge and discharge measurement points. State whether each pipe stays full, and record conductivity, solids, entrained air, fouling and expected cleaning access. These conditions can matter more than nominal pipe size.


Technology candidates


Electromagnetic meters are candidates for conductive liquids, including many wastewater streams. Select liner and electrodes for the actual service. Clamp-on ultrasonic measurement may help retrofit surveys on suitable pipes; suitability depends on pipe material, lining, acoustic path and fluid conditions.


Installation and selection checks


Choose a location that stays full and meets the selected manufacturer's installation requirements. Review grounding for electromagnetic meters and pipe dimensions and transducer mounting for clamp-on systems. Allow access for cleaning, inspection and verification.


Commissioning and ongoing use


Agree whether operators need instantaneous flow, daily totals, pump run comparison or an alarm. Verify pulse weights, engineering units and timestamps at both meter and logger. For reporting obligations, confirm the required method and calibration evidence before purchase.


What to send with your enquiry


Include the fluid and its properties; minimum, normal and maximum flow; pressure and temperature; pipe internal diameter, material and lining; connection requirements; available installation space; power supply; and the required pulse, analogue or digital interface.


State the decision the measurement must support, the required accuracy across the operating range, and any calibration, certification or reporting documents. Supply a marked-up pipe sketch and identify access or shutdown constraints so the quotation can cover installation and integration as well as the meter.


Sensor and equipment options


Browse these live products as selection candidates. Confirm the exact model and configuration against your application; listed ranges and options are not interchangeable.


Conductive-liquid candidate; confirm full-pipe operation, wetted parts, grounding and cleaning access.


Retrofit candidate where pipe and fluid conditions support an adequate acoustic path.


Listed base hardware: one DN50 electromagnetic meter, one optical turbidity sensor, one MPR800 8-channel recorder and one CM6024 supply. Confirm signal allocation and ranges.


Turbidity and flow answer different questions. A flow reading does not establish water quality, and a turbidity reading does not identify a contaminant. Select representative measurement points and a maintenance plan for both.


Build the complete measurement system


Process connection → selected meter or sensor → compatible signal input → local indication, totalisation or recording → optional telemetry and monitoring → agreed operator response.


Pulse: confirm pulses per litre or the required K-factor and receiving input frequency. 4–20 mA: agree the range, units, wiring and fault interpretation. RS485/Modbus: verify the exact register map, address, serial settings, scaling and byte order. A matching connector is not evidence of compatibility.


Keep flow rate and accumulated volume separate. Logging a 4–20 mA flow signal does not automatically provide reliable totalisation; specify and verify that calculation or read the meter's own cumulative total. Remote communications and cloud dashboards need an agreed device and integration path.


What the quotation should include


Exact meter model and size; wetted parts and seals; process fittings; transmitter and output configuration; power supply; indicator or logger; mounting and enclosure; cables; calibration documents; software and communications; and any requested configuration, installation or commissioning. Hardware listings include only their stated components and selected options.
