Open channel flow metering that keeps reading right.
Field service, calibration and installation for Hach flow meters — Flo-Dar, FL900 and more — plus new Hach equipment sales. One technician who knows your meters from the manhole up.
Hach flow meter service, start to finish
From choosing the right flow meter to keeping it accurate for years — we handle the fieldwork so your flow data holds up for permits, billing and planning.
Field Service & Repair
On-site troubleshooting and repair of Hach flow meters, loggers and sensors. We diagnose bad readings, failed sensors, communication problems and power issues in the field — and carry common parts to fix them on the first trip.
Calibration & Verification
Flow meter calibration and verification against independent measurements, with documentation you can hand to your regulator. Keep permit data defensible and your flow numbers trustworthy.
Installation & Commissioning
Site evaluation, sensor placement, mounting, wiring and programming for new Hach flow metering installations — from a single manhole to a plant-wide network.
Flow Monitoring Studies
Temporary open channel flow monitoring with Hach FL900 loggers for I&I studies, capacity analysis and model calibration. We deploy, maintain, retrieve and deliver clean data.
Preventive Maintenance Plans
Scheduled site visits to clean sensors, swap batteries and desiccant, update firmware and verify accuracy — so meters don't quietly drift until a report is due.
New Hach Equipment Sales
Help choosing the right Hach flow meter for your site, plus quoting, delivery and installation. One contact from selection through startup and ongoing service.
New Hach flow meters — sold, installed and serviced
We sell new Hach units and back them with local field support, so the meter you buy is the meter we keep running.
