PTFM 6.1 transit time meters measure the flow of clean liquids like water‚ glycol‚ oil and most chemicals. They’re ideal for flow studies‚ troubleshooting and calibration of other inline flowmeters.

The ultrasonic sensors strap on the outside of pipe and send a signal that penetrates all common metal and plastic pipe materials. Since the sensors don’t contact the fluid‚ you can take readings without shutting down the flow—no obstructions or drops in pressure. Clamp the sensors onto vertical or horizontal pipes ranging from 2 to 48". Ideal measuring range is 2 to 10”; contact USABlueBook's Technical Specialists for other sensor range options.

Calibrating your meter is easy with the user-friendly on-screen menu system and 5-button keypad. Just enter your pipe diameter‚ wall thickness and pipe material‚ and the meter indicates the optimum mounting method and separation distance for the sensors. Power the meter via an internal rechargeable lithium battery‚ or operate it continuously with AC power.

The PTFM 6.1 features a 12-million-point data logger and multi-digit totalizer‚ and can measure forward and reverse flow. For extended operation applications‚ the convenient on-screen "Flow Report" shows waveforms as well as total‚ minimum‚ maximum and average flow rates in a 24-hour daily summary. The USB port and included memory stick let you easily download data to a Windows® computer in CSV format for use with Microsoft Excel®. Included software makes generating flow reports easy.

Includes: watertight carrying case‚ transducer set‚ cables‚ AC adapter/charger‚ mounting clamps for pipes up to 30” OD‚ coupling compound‚ USB memory stick‚ software and manual.
