PTFM 1.0 Portable Transit Time Flow Meter
4Pages

The PTFM 1.0 Portable TransitTime Flowmeter is ideal to measure flow rate of clean, non-aerated fluids in full pipes. Accurate Flow Measurement of Clean Liquids with Non-Contacting Transducers Non-Contacting Flow Measurement Recommended for fluids like water, glycol, oil, and most chemicals. The PTFM 1.0 ultrasonic transducers strapon the outside of pipes from 50.2 mm to 1.2 m (2 in to 4 ft) diameter. The ultrasonic signal works through all common metal and plastic pipe materials. Transducers can be mounted without shutting down flow and there is no obstruction or pressure drop. User-Friendly Operating System Calibration is easy with the on-screen menu system. Just enter the pipe diameter, wall thickness, and pipe material. The PTFM 1.0 is powered by an internal, rechargeable NiMH battery or can be operated continuously with an AC power adapter. Each PTFM 1.0 includes a watertight carry case, transducer set, cables, and mounting clamps. Measures Clean Liquids in Full Pipes The PTFM 1.0 Portable Transit-Time Flow Meter is designed to measure clean, non-aerated liquids like water, chemicals, and oils with less than 2% solids or bubbles The ultrasonic transducers can be mounted on vertical or horizontal pipes. THE RIGHT METER FOR • Treated Water • Raw Water • Cooling Water • Chemicals • Hydraulic Oil • Demineralized Water • Water/Glycol Solutions • Diesel & Fuel Oils Measures Flow from the Outside of Pipes The PTFM 1.0 Portable Transit-Time Flow Meter works by measuring the “transit-time” or “time of flight” for ultrasonic sound pulses transmitted from one transducer to another. The transit-time in the direction of flow is faster than the transit-time against the flow. By comparing these differences with precision timing circuits, the PTFM 1.0 can accurately calculate the flow rate.

The choice of V, Z, or W mounting method depends on the application and pipe diameter. V-mount is the most common method while Z-mount is used for larger pipes or weak signal applications and W-mount for smaller pipes. Works with Common Pipe Materials Mount the ultrasonic transducers on the outside of metal or plastic pipes including carbon steel, stainless steel, ductile iron, cast iron, PVC, PVDF, fiberglass, copper, brass, aluminum, and pipes with bonded liners including epoxy, rubber, and Teflon. Avoid pipes made with porous materials (e.g. wood or concrete) or with loose insertion...
