We chose the Innova-Sonic 210i as our primary ultrasonic flow meter rental instrument due to it’s portability, accuracy, and ease of use. Every rental contains all the required accessories to begin taking flow measurements in five minutes or less. This unit works on pipes between 2 and 236 inches in diameter using clamp on or magnetic sensors providing non instrusive flow measurements for water and most clean liquids. In addition to real time flow rates the Innova-Sonic 210i also provides velocity, postive total, negative total, and net total measurements. The instrument includes a rechargeable lithium ion battery for up to 10 hours of runtime for portability or can be run from AC power for continuous monitoring. Data is written to an included 2 GB MicroSD card for easy transfer to a PC.
