Transmitters for Level, Density or Interface of Liquids



The continuous measurement of liquid level for exact indication and control of process sequences is among the most important measuring tasks in the chemical and petrochemical process industry.


intelligent buoyancy level transmitters are designed to measure liquid level, interface and density. The robust design and highly accurate measurement technology based on Archimedes buoyancy principle provide a best-in-class product for level measurement.  All Foxboro Eckardt buoyancy level transmitters offer continuous self-diagnostics. By eliminating all moving parts in their design, there is little or no maintenance required, further improving longevity and reliability.

CT Flex Tube Level Control


The CT (control throttling) Level Control has been an industry standard for over five decades. Its simplicity, reliability, ease of maintenance and rugged construction have made it popular where downtime for repairs could be critical to processes or where minimum maintenance is desirable.


The weatherproof pilot enclosure has been developed to completely protect the control from the elements and even hose cleaning operations.












CMAQ/CMAF Level Controls


The CMAQ and CMAF are snap-action, float operated level controls. They are equipped with the popular three-way Micro Valve unit actuated by two adjustable yoke type pusher arms. Adjustable pusher arms permit the control range to be adjusted easily and accurately to the range desired.











Model CADM-201 and CADMEX-201


These diaphragm operated liquid level controls are available with either a pneumatic or electrical control switch. The Model CADMEX-201 is supplied with an explosion proof SPDT Micro Switch. The switch is UL and CSA approved. The Model CADM-201 is supplied with the popular snap action, three-way Micro Valve. Ideally suited for for diaphragm motor valve control.










Model CQ-401 Float Type, Continuous Drain


The Model CQ-401 offers dual purpose action to automatically discharge vapor or liquid from a tank. The continuous drain valve is widely used in the bottom of fuel gas scrubbers to provide continuous drainage of the accumulated liquids and thus prevent transfer of the liquid to the burner section.











IMS 780 "RF" Capacitance Interface Measurement


This measurement system is a capacitance type device offering precise control of liquid interface. A non-fouling probe for continuous, reliable use is standard.












 Leveltronic Conductance Level Switch


The 9450 Leveltronic is a conductance level switch for detecting the level of conductive materials. When this material comes in contact with the electrode, the electrode is shorted and establishes a current path to ground. The unit responds to the short by actuating a relay.











Model CMAS-203/CMEASX-203 Level Control


The Model CMAS-203 utilitzes a stainless steel ball-type float and a three-way snap-action Micro Valve to provide a positive pneumatic output for control of liquid level.












These level controls provide electrical contact switch closure for alarm or control functions.  An explosion proof Micro Switch is actuated by two adjustable yoke type pusher arms, permitting the control range to be easily and accurately adjusted.












Remote Seals



Remote seals are used with Foxboro pressure transmitters when it is necessary to keep the transmitter isolated from the process. A sealed system is used for a process fluid that is corrosive, viscous, subject to extreme temperature, toxic, sanitary or tends to collect and solidify.
