The P7s ultrasonic flow meter measures the velocity of any liquid  through most pipes using  ultrasonic transducers. The flow measurement remains accurate even if temperature change is experienced. The meter can be used on water based applications and also other chemicals by entering in the  density and kinematic viscosity of the flowing medium for the automatic flow profile volume correction.  Maintenance of the ultrasonic flow meter is negligible because there are no moving parts. The ultrasonic flow meter uses a contapropagating transit time flow measurement technique and is able to function in clean and dirty media.

Many years of development and client feedback have enabled the design to be not only user friendly but easy to install and operate. Since the ultrasonic flow meter might be used outdoors and frequently transported, we have built it in such a way that the operator does not need to worry about comprimised flow measurement due to wet cables, connectors and electronics, which can be a problem with poorly designed portable flow meters. Everything you need to do a flow measurement  and log or graph the results is provided with the flow meter kit .

EESIFLO supports its worldwide ultrasonic flow meter clients by unique products, fast delivery and customer support.

Sierra’s next generation Innova-Sonic 210i ultrasonic flow meter succeeds at delivering portability and expanded functionality at significantly reduced cost.

The 210i is ideal for precisely measuring a wide range of liquid flows and temperatures. Our universal transit-time meter features a pushbutton interface, ergonomic handheld design and a large digital display that significantly simplifies set-up and data collection. And its high-powered ultrasonic pulse with improved digital signal processing requires just one set of transducers for a wide range of pipe sizes and materials including metal, plastic and concrete. 

The 210i provides a powerful and extremely user-friendly programming menu that includes instantaneous flow rate, positive total, negative total, net total, velocity, date & time, and daily flow results. It's 2 gig SD memory card promises high capacity data
logging and its rechargeable lithium battery supports continuous operation for a minimum of 16 hours. A fully field portable, lightweight, yet rugged and totally selfcontained flow measurement package, the Sierra 210i comes standard with a sturdy and convenient pelican carrying case, noninvasive clamp-on transducers installed into compact mounting racks (magnetic & cable mount), coupling compound and a startup CD. And itís easy to use. It sets up in five minutes or less.
While principally designed for clear liquids, the 210i operates effectively with the minimal quantity of air bubbles or suspended solids found in most industrial applications.
