A high pressure viscometer is a device to measure the thickness, or flow, of liquids under high pressures. A device of this type is important in many industries, particularly oil and gas chemical processing. How it works is fairly interesting. The viscometer squeezes liquid through a narrow opening and gauges how hard it is to do so. This in turn tells us how much fluid-like or solid-like behavior the liquid has. We need to know how viscous, or thick, a liquid is for so many things. For instance, a liquid that is thicker than its ideal level might not flow properly in pipes, leading to issues. Companies like ZONWON produce high pressure Viscometers that help businesses maintain a smooth flow of liquids.
