MSFM MCERTS Portable Area Velocity Flow Meter

An MCERTS-accredited, battery-powered portable area-velocity monitor for regulated discharge, storm overflow and sewer network studies. Five-year deployment on one battery pack.

SKU MSFM-MCERTS

  • MCERTS accredited — the data satisfies the regulator, not just you
  • Five-year battery life on a 12 V ATEX Li-ion pack
  • No weir, no flume, no civil works — velocity, depth and temperature direct
  • 2G/3G GSM/GPRS telemetry — monitor in a manhole, data on your desk
  • IP68 / NEMA 6P — built to sit underwater for years

Buy this one if…

You have a compliance obligation and the number has to be defensible to someone who is not on your side.

This is not a clamp-on flow meter

The MSFM is an insertion multi-sensor monitor for partially filled pipes and open channels. If your pipe is full, use a portable clamp-on flow meter instead — it is a better tool for that job.

MCERTS is the reason this instrument exists

Most flow meters are bought because someone wants to know a number. The MSFM is bought because someone is going to be audited on a number.

MCERTS is the certification scheme an inspector looks for when verifying flow data submitted under a discharge permit. The practical consequence: when you submit the data, the conversation is about the data. It is not about whether the instrument that produced it was adequate. That is a different and much shorter conversation, and it is worth paying for.

Five years on a battery

Remote sites become viable. Emergency overflows, rural pump stations, catchment monitoring points, storm outfalls — the places you most need flow data are exactly the places with no mains power. Running power to a manhole in a field costs more than the instrument.

The ATEX rating on the battery pack is not decoration. Sewers generate methane and hydrogen sulfide. A sewer is a potentially explosive atmosphere and should be treated as one.

No weir. No flume. No concrete.

The traditional way to measure open channel flow is to build a hydraulic structure and read the head over it. That works, and it means pouring concrete in a live sewer — civil engineering, a contractor, a permit, and a flow diversion. The MSFM determines flow from velocity, depth and temperature directly. It goes in and it starts logging.

The data comes to you

For inflow-and-infiltration work — where the whole point is correlating flow against rainfall across dozens of points — telemetry is not a convenience, it is the method. The system accepts data from telemetered monitors of any make, which matters if you are extending an existing network rather than starting one.
