iSOLV TUF333 Fixed Ultrasonic Clamp-On Flowmeter

The TUF333 is a transit time ultrasonic flow meter designed to work with clamp-on transducers, to provide accurate measurement of liquid flowing within a closed pipe, without the need for any mechanical parts to be inserted through the pipe wall or to protrude into the flow system. It takes just a few minutes to install and there is no need to shut down flow or drain the system!

When ultrasound is transmitted between the transducers, the speed at which the sound travels through the liquid is accelerated slightly by the velocity of the liquid through the pipe. When ultrasound is transmitted in the opposite direction, the flow of the liquid causes the transmitted sound to decelerate. The subsequent time difference is directly proportional to the flow velocity in the pipe. Having measured the flow velocity and knowing the pipe cross-sectional area, the volumetric flow can be easily calculated.

Application

• iSOLV Ultrasonic permanent / fixed Clamp On Flow meter TUF333 can measure almost all light homogeneous fluids (<5% solids). The basic requirement is that the fluid can
 conduct ultrasound and have an acceptable axis-symmetrical flow.
• Non invasive measurement, no interruption to process and no risk of contamination.
• With capabilities of measuring bi-directional flow and pipe diameter range from 13 to 2000mm.
• iSOLV TUF333 has many applications across many industries environment. They can be used for application like heat metering, chilled water energy metering, process metering,
 heavy fuel oil, condensate measurement and many more.
