Ultrasonic Type Level Sensors on Don Wolf & Associates, Inc.

The ULS-1 Series has proven ultrasonic technology combined with micro-controller improved performance in aerated liquid for tight spaces.
The ULS-1 Series Ultrasonic Level Switches are low cost, compact, level sensors with no moving parts, these small units are ideal for a variety of point level sensing applications especially where dependability and economy are a must.
These level switch units are suitable for high, low or intermediate level detection in practically any tank, large or small.

ULS-50

Gems ultrasonic switches are an excellent choice for a broad range of liquids including those with light coating or scaling type characteristics. Liquid examples include xylene, chromic acid and light cooking oils. FET or relay output provides a reliable switch interface with remote devices such as a PLC, SCADA or alarm. For maximum flexibility, the sensor is offered in general purpose and intrinsically safe versions with two probe lengths and polypropylene or PFA Teflon® materials.

ULS-60

These versatile, general purpose ultrasonic liquid level switches mount in the top of your tank and provide non-contact level detection from 6 inches to 12 feet. With two integral relays, you can control pumps, valves or alarm controls.

ULS-10 Series

The ULS-10 Series features a Tip Gap probe design for closer tank bottom access. The miniaturized, encapsulated electronic control unit may be supplied for remote mounting, or directly mounted on sensor in an explosion-proof, NEMA enclosure. FM-Approved, explosion-proof enclosures are also available.

ULS-11 Series

By integrating a 1 amp relay into the stem, we’ve made the ULS-11 our most compact ultrasonic unit. Yet, as unobtrusive as it is, the ULS-11 still delivers ultra-reliable solid-state performance in lengths up to 99 inches. Tip gap probe configuration places sensing point at 1/4 inch from probe tip for closer tank bottom sensing. Electronics are completely epoxy sealed for years of maintenance free service.

ULS-100 Series

The ULS-100 Series features our high performance sensor probe, 100:1 gain for tougher applications such as handling liquid temperature to 300°F (149°C) and pressure to 1000 psi. Explosion-proof and water-tight, cast aluminum enclosures are standard; FM Approved explosion-proof enclosures are also available.

UCL-200

Our premier ultrasonic sensors are available in three models: 1) Intrinsically Safe (P/N 201001): This two-wire model provides non-contact measurement up to 18 feet. Approved for use in: Class I - Groups A, B, C and D; Class II - Groups E, F and G; Class III; T3C environments. The transmitter is an excellent choice for use with solvent, hydrocarbon and petroleum type liquids; 2) General Purpose with Relays (P/N 201002): This three-wire model provides non-contact measurement up to 24.5 feet and features an integral relay for pump, valve or alarm control. This transmitter is an excellent choice for applications with dirty, coating, scaling or corrosive type liquids such as wastewater, crude oil or wax; and 3) Long Range with Relays (P/N 201003): This flange mounted, three-wire model provides non-contact measurement up to 40 feet. Its deeper measuring range makes this general purpose transmitter ideal for large bulk storage tanks, water or chemical reservoirs and waste stations. Media examples include chemicals, acids and slurries.

UCL-210

The two-wire UCL-210 Series level transmitters are mounted through the top wall of small or bulk tanks and provide non-contact measurement up to 12 feet. These general purpose devices are ideal for measuring intermediate bulk containers, day tanks, process vessels, plating lines and waste sumps. Our non-contact technology makes these transmitters an excellent choice for applications with ultra-pure, dirty, coating, scaling or corrosive type liquids. Media examples include ink, ultra-pure water, brine solutions, acids and wastewater.
