The EZ-View® variable area flow meters are durable and inexpensive direct reading instruments to measure a flow of oil, water and other liquids. They are very easy to install, and can be operated in any position: vertical, horizontal, inverted, etc., without sacrificing the quality of the measurement. They provide an instant readout of flow rate in closed piping systems. These flow meters are good solution for low pressure hydraulic system.

Flow measurement: from 2 through 380 lpm; maximum pressure: up to 22.4 bar.

The EZ-View® product line is made of impact-resistant plastic PPSU, allowing for excellent structural integrity and chemical compatibility with a wide range of industrial chemicals. The EZ-View® ensure the oil flow rate measurement in the range of 2 to 380 l / min of water from 2 to 380 lpm and water-based liquids from 2 to 100 lpm.

PPSU housing transparency allows visual inspection of the liquid state, as well as the flow rate of the internal read against the calibrated outer scale. EZ- View® requires no electrical connections. Flow straighteners placed at the inlet and outlet reduce sensitivity of the flow meter to turbulent flow. It does not require further straighteners nor other special installations.
