Liquid Flow Meters & Switches

Ultrasonic, Volumetric Vortex and Flow Switches for Liquids

Measure liquid flow rates quickly and more accurately with Sierra transit-time ultrasonic flow meters, vortex flow meters or thermal flow switches. Manufactured by Sierra’s team of flow engineers, our liquid flow meters are suited for even the most challenging liquid flow applications.

Choose a Liquid Flow Meter

Ultrasonic liquid mass flow meters, such as the InnovaSonic 203 ultrasonic flow meter, achieve high accuracy at low and high flows, and save time with no pipe cutting or process shutdown. Simply clamp the fluid flow indicator on the outside of the pipe for easy setup.

For volumetric flow calculations of influent and effluent water measurement, our economical InnovaMass volumetric vortex flow meters have a metering accuracy +/- 1.0% of reading over a 30:1 range. The insertion version of this liquid flowmeter offers easy installation with our hot tap retractor to make volumetric water flow calculations fast and easy. The on-board apps, such as Meter Tuning and ValidCal diagnostics, give you all the information you need to quick tune your meter to your application for the most accurate volumetric flow calculations.

Built for industrial applications, Sierra’s InnovaSwitch Flow Switch turns on a flow/no flow condition in both gases and liquids and is ideal for industrial pump protection. Perfect for high-temperature applications, the InnovaSwitch Level Switch is triggered on a level change of 0.8 mm and is ideal for tank leak detection.

Boiler MACT Certified

InnovaMass Vortex Flow Meters and InnovaSonic Ultrasonic Liquid Flow Meters are compliant with Boiler MACT regulations for inlet feed water measurement for area source boilers (40 CFR 63, subpart JJJJJJ) and for major source boilers (40 CFR 63, subpart DDDDD).
