Municipal Water & Wastewater
Flow meter and analyzer calibration for water and wastewater systems
Influent and effluent flow, lift station levels, aeration DO, and clarifier pH all feed the numbers operators report and act on. We calibrate, verify, and repair that instrumentation on site and document the results so your records show how each instrument actually performed.

Where calibration shows up
Where measurement drives treatment decisions
Most municipal systems depend on a handful of instruments that carry a lot of weight. When one drifts, it can affect chemical use, pump cycling, and the data behind permit-related reports.
Influent and effluent flow
Magnetic meters, open-channel flumes, and weirs that measure what enters and leaves the plant, often tied to discharge monitoring records.
Lift stations
Level transmitters and floats that start and stop pumps, plus the flow data used to check pump performance and drawdown.
Aeration and biological treatment
Dissolved oxygen sensors that control blowers. A drifting DO reading can mean wasted energy or under-aerated basins.
Water treatment and distribution
pH, conductivity, and flow instruments used for chemical feed, finished water quality, and system balancing.
Common instruments
Instruments we calibrate and repair for this work
These are the device types we see most often at municipal plants and in collection systems. Each links to the service page for that instrument.
Services
What we handle, from first check to replacement
Our technicians work at treatment plants and lift stations across Minnesota and the Midwest. Portable instruments can also be shipped to us for mail-in service.
On-site calibration
Calibration of flow, level, and analytical instruments where they are installed, scheduled around plant operations and staffing.
Verification
Documented flow meter verification for operators maintaining Minnesota Pollution Control Agency (MPCA) permit records, plus checks on level and analytical instruments.
Troubleshooting
Tracking down erratic flow totals, level signals that do not match the wet well, and analyzer readings that disagree with grab samples.
Repair
Repair of transmitters, sensors, and electronics, with calibration afterward so the instrument returns to service with a current record.
Equipment sales
Replacement meters, sensors, and transmitters when repair no longer makes sense, selected for the application and the existing installation.
Calibration program
Why calibration matters
Treatment decisions, energy use, and reporting all rely on instrument data. Regular calibration keeps that data defensible.
01
Accuracy
Flow totals and analyzer readings are only as good as the instruments producing them. Calibration identifies drift before it shows up in your reports.
02
Reliability
Lift station controls and aeration loops act on what sensors report. Instruments that read correctly keep pumps and blowers working as intended.
03
Reduced downtime
Finding a failing sensor during a scheduled visit is far easier than chasing a lift station alarm after hours.
04
Documentation
Calibration certificates record what was tested and how the instrument performed. You can view, download, and share them in the online portal.
