 Innova-Sonic Model 210i Ultrasonic Portable Flow Meter
 
Ultrasonic Portable Liquid Flow Meters
 
Sierra's next generation Innova-Sonic® 210i ultrasonic flow meter succeeds at delivering expanded functionality and field portability.  The 210i is ideal for precisely measuring a wide range of liquid flows and temperatures. This universal transit-time meter features a pushbutton interface, ergonomic handheld design and a large digital display that significantly simplifies set-up and data collection. 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.
 
While principally designed for clean liquids, the 210i operates effectively with the minimal quantity of air bubbles or suspended solids found in most industrial applications.
 
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. Its 1GB SD memory card promises high capacity data logging and a rechargeable lithium-ion battery supports continuous operation for a minimum of 16 hours.
 
A fully field-portable, lightweight, yet rugged and totally self contained flow measurement package, the Sierra 210i comes standard with a sturdy and convenient pelican carrying case, non-invasive clamp-on transducers installed into compact mounting racks (magnetic & cable mount), coupling compound and a start-up CD. And it's easy to use. It sets up in five minutes or less.

 Innova-Sonic 205i Insertion Ultrasonic Flow Meter
 
Insertion Ultrasonic Flowmeters and Readers
 
Innova-Sonic™ Model 205i is commonly ordered with standard clamp-on transducers, however, insertion transducers are a good choice when their are signal strength issues due to difficult piping configurations. To eliminate issues with pipe wall thickness, pipe liners, and/or pipe wall deposits, the 205i insertion transducers will assure signal strength and performance of the instrument.  The transducers can be used on pipes that range in size from 2-inch to 400-inches (50mm to 10000mm).

 Innova-Mass® Model 241 VTP (Multivariable Vortex Meter)
 
Insertion Multivariable Mass Flow Meter
 
A unique insertion multivariable vortex mass flow meter, the Model 241 is a true workhorse in large pipe applications, high pressure applications and numerous geothermal steam applications.
 
Our  Model 241 provides a direct reading of mass flow rate from a single entry point in the process line and provides analog and digital outputs of five process variables: mass flow rate, volumetric flow rate, temperature, pressure, and fluid density. The unique insertion design has probe lengths from 2-inches up to 72-inches and can measure air up to 67000 scfm and saturated steam up to 330,000 pounds/hour.  In addition, the instrument  is available in a high-pressure version capable of mass flow measurement of gases up to 5000 psig. The Model 241 has emerged recently as the proven instrument of choice in geothermal steam applications across the globe.  The ability to sense all process conditions in a single location greatly improves measurement accuracy and eliminates the costly requirement for additional line penetrations associated with traditional mass flow measurement systems.
