 203i Thumb

Innova-Sonic® 203 Economical

New to the offering, the Innova-Sonic® 203 has been optimized for customers still looking for good performance, but needing a lower cost, less feature rich option for dedicated clamp-on ultrasonic metering.

 

 205i Thumb

Innova-Sonic® 205i High Performance

The Innova-Sonic 205i is Sierra’s highest performing dedicated clamp-on instrument incorporating the latest developments in digital signal processing to offer excellent accuracy and repeatability for a wide variety of liquids.

 

Innova-Sonic® 210i Portable

The Innova-Sonic 210i portable clamp-on ultrasonic meter has received a complete repackaging into a smaller more light weight, hand-held configuration including new brighter display and pushbuttons.

 

Innova-Sonic® Model 205i Insertion

The Innova-Sonic 205i insertion features insertion transducers that can be used on pipe sizes ranging from 2" to 400" (50mm-10000mm). The key benefit is the high signal strength achieved by using insertion transducers so that pipe wall, pipe liner, and pipe wall deposits do not affect instrument performance.

Live-Tap (Hot-Tap) Flow Switch
The Livetap (LT) allows for the safe insertion and removal of Innova-switches without interrupting the flow in your pipelines. With a pressure rating to 300 psig and a temperature rating of 390F, the Livetap can be used in the most demanding applications. An External extraction gauge lets you know when the switch is clear of the valve and dual safety restraints aid in the prevention of accidents.
