Who we are
Greyline is a worldwide leader in ultrasonic instrumentation for industrial and environmental markets. We develop, manufacture and market industrial flow and level monitoring instruments including ultrasonic flow meters, open channel flow meters, and level monitors and controllers.
Greyline’s primary market is environmental – especially water and wastewater treatment systems. Greyline offers products which are easy to use, and with excellent customer support both before and after sale. The ultrasonic flow and level meters don’t contact the fluid, so there is little maintenance and the product is to install.
With years of steady growth, Greyline products are sold and supported worldwide.
