Courtesy: Sierra InstrumentsSierra Instruments has announced the introduction of their transit-time ultrasonic flow meters. The lineup now includes improved next generation Innova-Sonic 205i and portable 210i models. 

The Innova-Sonic 205i is a clamp-on instrument incorporating the latest developments in digital signal processing to offer accuracy and repeatability for a wide variety of liquids. The Innova-Sonic 210i portable clamp-on ultrasonic meter has received a complete repackaging into a lightweight, hand-held configuration including new brighter display and pushbuttons.

The design of the Innova-Sonic 203 focuses on the measurement of water flows in HVAC, irrigation, and other water applications. Ideal for pipes up to 48” in diameter, the 203 is accurate 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, 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.

For the Innova-Sonic 205i, accuracy improves to +/-0.5% of reading, repeatability to +/-0.15% of reading, and pipe capacity increases to 200”. Shortcut buttons have been added to the main interface for flow, totalized flow, velocity, fluid, signal and diagnostics to make set up and data collection even easier. New high temperature clamp-on and insertion options have been added, making the unit more flexible. PCA’s inside the meter have been modularized, enabling field swap out for easy repairs or upgrades.

The 205i also features a large alpha-numeric display, parallel operation of positive, negative and net flow totalizers (with user-selectable scale factors), and configurable pulse frequency, and analog outputs plus relay and open collector outputs. SD data logging capability is included and energy monitoring is fully supported for both heating and cooling applications.

The portable 210i provides a powerful and extremely user-friendly programming menu that includes instantaneous flow rate, positive total, negative total, net total, velocity, date and time, and daily flow results. Its 1GB SD memory card is for high capacity data logging while a rechargeable lithium-ion battery supports continuous operation for a minimum of 16 hours. The 210i comes standard with a pelican carrying case, non-invasive clamp-on transducers installed into compact mounting racks (magnetic and cable mount), coupling compound and a start-up CD. The meter set up time is less than five minutes.
