The CIC-2005 series has no moving parts and is designed to output both analog and digital signals for PID feedback control of pumps, motors, valves, robotics, actuators etc. The CIC-2005 series ranges of flow control are from 0.03 GPH to 475 GPH, and can be re-ranged in the field or by the factory to 'dial in' even greater accuracy and precision for custom application flow rates (See Re-ranging).
The BI-7000 series is built with a proportional valve and designed to meet the most difficult low flow control applications. Units provide full scale control accuracy of +/-1% under 2 milliliters per minute (mLm or cubic centimeters per minute) with additional standard model ranges to 500 mLm (ccm).
