VorTek Instruments recently released the SonoPro U44 Portable clamp-on ultrasonic flowmeter. The SonoPro U44 Portable offers high-accuracy transit-time ultrasonic technology to deliver accurate and economical flow metering in a portable design. The innovative design incorporates matched precision transducers and signal processing circuitry to accurately measure the flow of most liquids over a wide range of velocities. Clamp- on transducers create no wear, zero pressure loss and do not require process interruptions for installation. With the addition of external temperature inputs, the SonoPro U44 Portable can provide a reliable (BTU) thermal energy measurement.
