Detecting liquid levels in confined spaces in machines and facilities can pose problems. For these types of applications, Baumer developed its CFDK 25 capacitive sensor. The 52.4 x 25-mm flat housing design has a height of only 6 mm and has an available mounting frame. In addition to attachment with two screws, the frame allows installation with cable ties, a Velcro fastener or glue.
The capacitive sensor has four fixed nominal sensing distances from 2 to 15 mm offered in a chemical resistance housing made of Polyamid 12 plastic.

A precision off-the-shelf liquid level sensor, developed for motorsport, military and industrial applications the ‘R-Series’ is now available from Gill Sensors. The sensor has no moving parts, utilising advanced capacitive technology to accurately monitor the liquid level.
Compatible with fuel, oil, water and other specialist liquids, the R-Series liquid level sensor features an SAE 5-bolt flange mount as standard and is manufactured to the end users’ exact length requirement, avoiding the need for any mechanical adjustment by the user. With fully integrated electronics producing a configurable 0-5V analogue output, the R-Series is seen as an ideal ‘drop-in’ solution for most liquid level applications.
In addition to the standard R-Series sensor, Gill Sensors has also introduced an ‘Rxl’ variant for applications where a very long sensor is required. This variant of the R-Series utilises the same SAE 5-bolt mounting pattern but introduces additional mechanical strengthening features to support the longer probe. This sensor targets industrial applications that require precision liquid level measurement of storage tanks up to 3m in depth, says the company.

OleumTech today announced the release of the H-Series, hard-wired continuous level sensors, which complements its existing wireless liquid level transmitter offering. The H-Series is a digital level sensor based on a field proven magnetostrictive technology, which makes it ideal for Oil & Gas, Food & Beverage and other level measurement applications requiring process control, leak detection or inventory control.
With a low power design, H-Series sensors can be multi-dropped on a RS485 network, providing Modbus connectivity to a RTU or PLC controller. By combining low power requirements with high resolution of 0.01″ across full span, the H-Series provides the ultimate performance and reliability.
“The new liquid level solution is ideal for short distance runs to the RTU or existing legacy installs where conduit and wiring is available,” said Vrej Isa, COO at OleumTech. “But it’s the innovative packaging with the ease of installation that will set us apart from the competition.”
The Liquid Level Sensor is capable of providing product level, interface level and temperature measurement in virtually all tank sizes (up to 60 feet tall) in a variety of liquids such as crude oil, solvents, water, diesel, kerosene, gasoline and other media. The H-Series is available in a rigid stainless steel or flexible PVDF package.
The H-Series design meets applicable regulatory requirements for use in hazardous environments. OleumTech additionally offers an optional barrier board that limits the current, voltage, and total energy delivered to the sensor in a hazardous area or flammable environment. The barrier boards also provide extra protection to the level sensor from lightning strikes or any surge damage.
Bent Arm Liquid Level Sensor

Chicago, IL – Chicago Sensor, Inc. introduces our new bent arm stainless steel liquid level sensor: the FLT223 series.

The new design offers users the ability to sense liquid level 1.5” below the mounting point of the switch, but without the need for a custom bracket as would be required with a vertical-mount switch. The switch mounting hole can be above the high-level point in a chamber, avoiding long-term issues with leakage or caustic chemicals that may resist normal techniques for sealing the mounting hole.
Developed by Chicago Sensor for an aviation engineering client, the switch can be used in a variety of applications. The Company keeps small quantities of the switch in stock and ready for immediate shipment at chicagosensor.com. Order quantities in the thousands can generally be produced in just three to four weeks. The switch offers excellent value, with pricing under $14 per piece in quantity.
