Transit-Time Ultrasonic Flow Meters Don’t Need to be Expensive

Sep 28, 2011

When you think about clamp-on, transit-time ultrasonic flowmeters, the first thought that usually comes to mind is the value that stems from the convienence and accuracy for liquid flow measurment–no pipe cutting, very high accuracy and reliability, no hassles.  But, that value does come at a price, and it is worth it if you take into account total cost of ownership.

However, what if you need to make an accurate water or water based fluid measurement and can do without some of the bells and whistles common with high-end transit-time ultrasonic flow sensors.  The recent introduction of the Innova-Sonic 203 , a slightly less feature rich and application flexible instrument compared to the flagship Innova-Sonic 205i, you get an instrument maximized for water flows, HVAC, irrigation, and other water applications which typically are under great budgetary pressure.  Take a look at the pricing here to compare the 203 to the high end 205i.

Ideal for pipes up to 48” in diameter, the 203 still promises solid accuracy to +/-1.0% of reading, repeatability to +/-0.3% of reading and a temperature range of 32°F to 140°F (0°C to 60°C).  The 203 offers low power consumption and high reliability at an economical price. An easy to read display and clear, user-friendly menu selections make using the instrument simple and convenient. It can be configured via keypad without any additional programming devices.
