Bi-Directional Flow Meter is ideal for monitoring pump performance as well as measuring fluids in hydraulic circuits and cooling systems where flow is measured in both directions.
The Bi-Directional Variable Area Flow Meter is a high performing oil and water meter available in aluminum, brass, or stainless steel to meet system requirements. It measures bi-directional flow of oils and water, such as in test kits and mobile hydraulic systems. The high pressure operation, multiple ports available, and unrestricted mounting make this flow meter versatile, customizable, and easy to install. The all metal pressure vessels provide a safe and reliable, performance.
