ProSense CLC series conductive-liquid level controllers detect and control tap water, seawater, sewage, chemical solutions, coffee, milk, etc in dual-probe, pump-up (fill) and/or pump-down (drain) applications. A wide adjustable sensitivity range is included for a variety of liquid types. ProSense pulses the probes with a DC voltage to prevent potential electroplating issues, while the output relay can control pumps, solenoids or valves to automatically lower, raise or maintain the liquid level in the tank.
Sensor with chip measures all applications
VEGAPULS 6X radar sensor measures in every level application by using a new radarchip, simpler operation, and a self-diagnosis system that immediately detects damage or interference, and ensures higher availability and safety, which enables it to be the first 80-GHz sensor that's SIL certified. VEGAPULS 6X also complies with IEC 62443-4-2 security standard. Because it can handle any application, users don't have to worry about choosing between technologies, frequencies or instrument versions.
U-Gage T30 ultrasonic sensors with dual discrete outputs from Banner Engineering feature simple, pushbutton programming to provide flexibility in demanding environments, such as gauging when sensing liquid levels in a tank or sensing most clear materials. Each sensor includes two discrete outputs, which may be programmed independently with different window limits or together with identical limits. Each output can be set with a sensing distance setpoint centered within a 10 mm window.
Patented Acurage with guided-wave radar (GWR) is reported to be the first auto-calibrating radar gauge for true level reading and instant-spot, smart calibration. It's an ASME-approved level measuring instrument that displays the level of process fluids in real-time via digital display and a built-in, sight-glass tube. Acurage also features a built-in, safety-ball check system to protect users from accidentally spilling process liquid in the unlikely event of glass breakage.
Ultrasonic, non-contact with LED
LUS211 ultrasonic, programmable, non-contact level sensor with local LED display measures solid and liquid levels, and isn't susceptible to material build-up or damage. It also features a rotatable, stainless-steel housing and capacitive touchpad menu navigation to simplify programming. IO-Link, switching or analog outputs and easy vessel geometry parameterization provide flexibility. LUS211 can determine tank fill percentage or volumes in gallons or liters, and is ideal for level sensing in non-pressurized vessels.
Model W-200 Pilotrek two-wire, 80-GHz (W band) pulse-burst radar level transmitters include the WP-210 model for water/wastewater processes and measuring liquids, masses and emulsions. W-200 has a measuring range up to 1,181 in. for liquids and masses, achieves accuracy of ±0.787 in,, and has a 1 in. and 1.5 in. encapsulated horn antenna that allows easily installation. It also features an integrated design with IP68 protection, user-friendly threshold management, and upcoming Ex variant.

EJXC80A with compensation capillary type diaphragm seal is the latest in the EJX differential pressure level series. The compensating capillary balances the volume and temperature of fill fluids between high and low pressure side capillaries. EJXC80A reduces the influence of ambient temperature drift caused by day-to-night, season-to-season, or shady-to-sunny swings. Combined with DPharp sensor, this solution provides stability for all DP level measurements.
Adaptable with ultrasonic
UC18GS ultrasonic sensors detect fill levels regardless of color and other optical properties. It has a sound beam radius that's easily adjusted with pushbuttons on the instrument or via software. UC18GS also features a measuring range up to 1,000 mm; very small dead bands of 30 mm with response of 70 mm; IO-Link 1.1 infrared interface IrDA; 2x push-pull switching output or 1x push-pull switching output and 1x analog output (current/voltage); ambient temperature range of -25 to 70 °C; and IP67 protection.
1100 Series magnetic level indicator (MLI) is reported to use one of the widest, most visible indicating flag designs, which can be easily read from 250 feet (76 meters). Along with its patented, 200° vista viewing angle indicator and a five-year warranty on the chamber, 1100 Series MLI includes nitrogen-purged and sealed indicators. With designs for flashing/boiling applications and cryogenics, SOR can customize a magnetic level indicator for rigorous conditions.

Differential pressure transmitters deliver accuracy of ±0.065% of calibrated span (standard) to ±0.04% of calibrated span (optional). Available with direct- or capillary-mounted diaphragm seals, pressure transmitters for static pressure can serve at up to 1,035 bar (15,000 psi). Their 97% safety failure ratio achieves what's reported to be the best avaiable safe failure fraction (SFF). They work with all liquids and in closed or open tanks.

DJ durable level detectors provide high-point level detection of bulk solids in dusty environments and on vessels with vibrators. They require no adjustments and are virtually wear-free. DJs have no moving parts, gaskets or seals, and rely on mechanical oscillations to determine if the probe is covered or uncovered. Signals from DJ operate a single-pole, double-throw relay in the control unit, while the relay contacts actuate alarms, indicator lights or control devices.
