The new PTFM 1.0 Portable Transit Time Flow Meter from Greyline Instruments Inc. (Massena, NY) is designed to accurately measure clean liquids like water, oils, and chemicals and is ideal for calibrations, troubleshooting, spot checks, and balancing flow, says the company. Set-up through the handheld meter is fast with a user-friendly, 5-key menu system. The clamp-on transducers mount on plastic or metal pipes and ultrasonic signals are injected through the pipe between the two sensors. It works on full pipes with diameters from 1/2 to 48 inches. The Greyline PTFM 1.0 features a large backlit display, totalizer, 4-20mA output, and a data logger with USB output. It operates for 24 hours on internal rechargeable batteries and push-button sleep mode extends the battery life.
