Greyline Instruments Inc

Plants and municipalities that need to measure liquids without ever touching them rely on ultrasonic instruments to do the job. That is what we make. Greyline Instruments Inc designs and builds ultrasonic flow and level monitoring equipment from our facility in Long Sault, Ontario, near Cornwall.

Our instruments include open channel flow monitors, ultrasonic level transmitters, and flow meters. They use a non-contacting sensor with no moving parts, so they hold up well in dirty or corrosive liquids where ordinary meters fail. Customers find them in water and wastewater treatment, along with a range of process and industrial settings.

We have been at this since 1986 and ship our products to customers around the world. Our own research facility lets us test both closed pipe and open channel systems before they leave the building. If you need reliable flow or level measurement for a tough application, contact us and we will help you pick the right model.
