Continuous Level Transmitters & Sensors

Polysulfone level sensor ideal for shallow tanks and reservoirs. Compact and versatile with all-plastic wetted parts and a broad choice of mountings and float materials. Designed for high-volume OEM applications. Stem length to 20" (50 cm), 4 mm resolution.

Combines the rugged durability of stainless steel or brass with a compact design for restricted spaces. Ideal for tanks less than 2 feet deep. Stem length to 20" (50 cm), 4 mm resolution. SS or brass mountings and stems for broad media compatibility.

Completely electronic with analog output — can be combined with Gems Digital Bargraph Display and Level Cube Receivers for a complete tank gauging system. Lengths to 144 inches (3658 mm), ¼ inch (6 mm) resolution. Stainless steel or brass construction. Now available with stem-mounted 4–20 mA signal conditioner.

Designed to monitor chemical tanks and vats — provides resistance to corrosive liquids and vapors. The XMP-800 delivers proportional voltage output. Compatible with Gems digital bar-graph displays and Level Cube Receivers. Ideal for chemical processing and aggressive media applications.

A durable, low-cost solution for applications that do not require high-resolution output. The XM-860 provides a simple, economical and reliable means of continuous liquid level monitoring where cost is a primary consideration and basic analog output is sufficient for the application.

Rugged transmitter designed for tanks up to 18 feet (5.48 m) in depth. Heavy-duty stems resist turbulence and float options accommodate liquids with minimum specific gravity as low as 0.53. Standard resolution ½ inch (13 mm); higher resolutions available on request. The XT version includes signal conditioning for direct 4–20 mA output.

Rugged large-tank float transmitter designed for deep tanks up to 18 feet (5.48 m). Heavy-duty stems resist turbulence and provide stable level measurement in tanks prone to liquid movement. Float options for liquids with specific gravity as low as 0.53. Compatible with process and OEM applications requiring long-stem level measurement.

Non-contact ultrasonic level sensor with no moving parts, built for general-purpose small-tank applications. Level measurement up to 49.2 inches (1.25 m) with 4 relays for switch or control functions and continuous level output. Ideal for challenging fluids where contact sensing is unsuitable — corrosive, sticky or dirty liquids.

Two-wire ultrasonic transmitter providing non-contact level measurement up to 26.2 feet (7.98 m). Built for challenging ultra-pure, corrosive or waste liquid applications. Loop-powered 4–20 mA output simplifies installation with just two wires. Ideal for larger tanks and open channels where float or guided wave solutions are impractical.

A no-moving-parts continuous level sensor using advanced guided wave radar technology for reliable performance in the most challenging marine and industrial tank applications. Accuracy of ±0.2 inches (±5 mm) — independent of dielectric constant, temperature, pressure and density variations. Suitable for liquids with foam, vapour or turbulence. Standard 4–20 mA and HART output. Adaptable to fit all tank types and ideal where float or ultrasonic sensors may be affected by media characteristics.
