AM-ULF-P Portable Ultrasonic Flow Meter

A clamp-on ultrasonic meter reads the velocity of the liquid through the pipe wall: two transducers are pressed onto the outside of the pipe with couplant, the instrument measures how the sound behaves in the flowing stream, and no wetted part, no pressure drop and no pipe disturbance follows. The AM-ULF-P puts that pair in a high-strength case with a 20-hour Ni-MH pack, a 2-line backlit display, a 4×4+2 keypad and a built-in thermal printer.

Buy it for what a fixed meter cannot do: a survey across a dozen measuring points, a week of temporary metering during a shutdown, a check on a meter you already pay for, or a line you cannot cut. It is not your permanent instrument. Twenty hours of battery, an RS485 port and a thermal printer mean readings, not a control signal — the loop, the hazardous area and the year-round record belong to a fixed installation.
