One-piece acrylic variable area flow meter for low volumes

Variable area flow meter for measuring small flow rates of liquids and gases. The metering channel is machined directly into a monolithic acrylic body, making the instrument sturdy and economical. The end fittings are removable and available in several materials.

Features

• Measuring ranges from 4…50 cm³/min up to 1…10 l/min for water
• Measuring ranges from 0.04…0.5 l/min up to 100…700 l/min for air
• Connections from ⅛" to 1" NPT female
• Removable fittings in PVC, brass or stainless steel
• Maximum pressure 6.5 bar, maximum temperature 65 °C
• Accuracy from ±2 to ±5 % of full scale

Operating principle

The medium rising through the metering tube pushes the float upwards until it settles at a height proportional to the flow rate. The meter must be installed vertically with upward flow.
