Key Instruments Flow Meter
The Key Instruments FR2000 series variable area flow meter measures the gas flow rate of 0.4L/min to 5L/min. This is a standard, precision-machined, acrylic flow meter for liquids or gases. It has direct-reading air or water scales and is available in either English or metric scales. This is a durable and affordable product that provides highly repeatable results. It can be configured with a control valve on the inlet. The fittings and the valve are specified in brass and the O-rings are provided with Buna-N. These precision-machined, 1-piece, acrylic-body blocks can handle demanding projects and mounting panels along with high durability. It is used for many non-corrosive, low-pressure air, water and gas flow applications.
Note:
Please ensure you have selected the correct gauge for air, gas, or water.
