Clamp-on flow meter catalog

Every clamp-on ultrasonic flow meter Seztec USA supplies — plus the area-velocity meters we sell when clamp-on is the wrong answer. Specifications transcribed from the manufacturer datasheets, not from marketing copy.

Comparing named instruments?

We compare eleven portable clamp-on ultrasonic flow meters side by side — including seven we do not sell — on pipe range, accuracy, transducer temperature, battery life and price, with transit-time and Doppler tabled separately and every figure taken from the manufacturer's datasheet. See the portable comparison →

Portable clamp-on — transit-time

Clean liquids. You carry these to the pipe: surveys, energy audits, hydronic balancing, meter verification, leak detection.

Portable clamp-on — Doppler

Dirty liquids. Sludge, slurry, raw wastewater — the fluids transit-time cannot see.

Fixed clamp-on — transit-time

Clean liquids, continuously, into a control system. 4–20 mA, Modbus, RS232.

Fixed clamp-on — Doppler

Dirty liquids, continuously. Wastewater plants, mine dewatering, effluent lines.

Area velocity — not clamp-on

For pipes that are not running full, and for open channels. Clamp-on cannot measure these. These can.

Tell us the pipe. We will tell you the meter.

Pipe size, material, wall thickness, lining, fluid, and available straight run. That is everything an application engineer needs to give you a real answer.
