Flow, Level & Valves

Liquid level control is crucial to the operation of your laboratory. Cole-Parmer offers a complete selection of liquid level control products including float switches, optical sensors, and ultrasonic transmitters to meet your technical needs and price point. A float switch liquid level control product is ideal for cost sensitive applications where high precision is not required. Optical sensors provide a compact and economical solution liquid level control and have the added benefit of better accuracy and no moving parts to wear. Ultrasonic transmitters handle the more demanding applications and combine high accuracy, contact free operation, and a 4 to 20 mA signal output for control functions. Intrinsically safe ultrasonic transmitter models are also available.

Cole-Parmer offer an extensive range of flow meters for liquid, gas applications, and steam applications. Cole-Parmer’s meters are simple to install and we offer flow meters for measuring flow rates from 0.0002 mL/min to over 400 LPM and for gases from 0.02 mL/min to over 700 m3/hour. Our range of flow meters include variable area, magnetic, mass flow, ultrasonic, paddle wheel, turbine, vortex, gear, and corliolis.

To find the right flow meter for your application use Cole-Parmer’s on-line flow meter quick search. Alternatively contact our Application Specialists for free technical support and let us bring over 50 years of flow control experience to help solve your application needs.

Our valve selection includes a wide variety of products from simple and inexpensive plastic ball valves to solenoid valves for laboratory and industrial uses. Other types of valves include check, diaphragm, eleptical, metering, needle, pinch, proportioning, and stopcocks. Whether it's actuated ball valves for industrial uses or need valves for the laboratory, Cole-Parmer has your valving solution.

If you have questions about liquid level control contact one of our Technical Experts.
