Apex Water Flow Controllers and Meters

Apex Liquid Flow Controllers combine accurate measurement with fast control for distilled and de-ionized water. Just like with our Apex Gas Flow Meters and Controllers, the Apex Water Flow Meters and Controllers use differential pressure measurements across a laminar flow stack to measure flow precisely. Although used for water flow applications, the Apex Water Flow Meters and Controllers have the same communications and controls as our gas units and are easily integrated into any system. We are here to help in the configuration of your water flow unit to any application or control system you may have. We provide control and meters from flows as low as 0.5 CCM (cubic centimeters per minute) to 10 LPM (liters per minute). All units come standard with constant in-line temperature measurement as well as the option to add pressure measurement. There are also other options that include a portable battery pack for the water flow meter as well as special fittings and electrical connections to fit your application. Please consult your Apex sale representative if you would like to discuss additional options for your Apex Water Flow Controller or Water Flow Meter.
