Tank Level Applications

Tank Level Measurement

Senix non-contact ToughSonic® ultrasonic sensors offer cost-effective, continuous level measurement for small and large tanks. They install at the top of the tank, are not immersed in the liquid and can measure both benign and chemical liquids.

Tank Level Measurement

  • Non-contact – nothing touches the liquid
  • Easy to install at the top of the tank into standard fittings
  • Use indoors or outside, in metal or plastic tanks
  • Connects to other industrial equipment
  • Measures a wide variety of liquids and liquid environments
  • Accessories to display, alarm and control liquid levels
  • Wireless option sends tank levels to a LAN or the cloud
  • MRO & OEM tank setup duplication without re-calibration
Applications

Inventory
Batch control
Low and high level alarms
Empty, fill or maintain level
Pump & valve control

Tank Level Measurement Environments

Water & Mild Liquid Tank Level Measurement

Water Level Sensing

ToughSonic General Purpose sensors easily handle these liquids. Rugged construction, corrosion resistant materials, a wide environmental operating range and a liquid-tight IP68 ingress rating make them ideal for indoor and outdoor use – even in salt water and hydrogen sulfide (H2S) environments.

Products are offered in a variety of distance ranges to accommodate tanks ranging from 6 in (15 cm) to 50 feet (15.2m), with various mounting threads and accessories available. All ToughSonic sensors include analog, switch and data interfaces and compatible setup software, included at no charge.

Chemical Tank Level Measurement

ToughSonic CHEM sensors expand the range of environments in which our sensors operate. Some common chemicals can damage or corrode sensor materials, even 316 stainless steel. Transducer elements and bonding adhesives are also susceptible. Our CHEM sensors avoid these problems by using a continuous injection molded housing of Polyvinylidene fluoride (PVDF), a highly non-reactive thermoplastic that resists solvents, acids and hydrocarbons.

CHEM sensors have both top and bottom mounting threads and include a potted-in, PUR-jacketed, UV resistant cable. Verify your chemicals and operating temperatures with this compatibility chart. All ToughSonic sensors include analog, switch and data interfaces and compatible setup software, included at no charge.

Tank Level Measurement in Hazardous Areas

Our SafeSonic 25-L is a two-wire, 4-20 mA, loop powered, intrinsically safe sensor CSA approved for use in hazardous areas only in the United States and Canada. Pre-calibrated for a range of 1 to 25 feet (0.3 to 7.6 meters), it can be user-configured using SenixSAFE-L software from the non-hazardous side of a safety barrier with our Remote Configuration Device. The 2-inch NPT threaded PVDF transducer maintains chemical compatibility with most liquids.

Sensor Outputs & Interfaces

SenixVIEW Software

The ToughSonic General Purpose and ToughSonic CHEM product lines all have multiple analog and switch outputs compatible with most industrial equipment, plus a serial data communications interface for SenixVIEW software setup or user applications.

Analog outputs can be proportional to tank level or volume. Switch outputs can control pumps and valves, or indicate low or high alarm conditions. Simple level controls can be created with only a sensor and an external relay option. Outputs are user-configured with SenixVIEW setup software. Setups are permanently stored in the sensor, and can be saved and duplicated in other sensors without re-calibrating. Some models have 5 simultaneous outputs while others have 2 SenixVIEW selected outputs. All sensors have a serial data interface, and all outputs operate concurrently.

SafeSonic models are available as either 4-20 mA loop powered or with RS-485 Modbus communications.

Accessories & Options

Displays, Alarms and Packaged Systems

Digital controller accessories display level measurements and/or provide outputs to control other equipment. Tank levels can be displayed as level or volume in any units. Relay output options control pumps, valves or level alarms. Measurements can also be re-transmitted to additional displays or equipment at other locations. Other features include:

  • Sunlight readable outdoor displays with large digits
  • Pump control sequencing for multi-pump systems
  • Volume calculations for horizontal cylindrical tanks or other shapes

Displays are sold individually, with or without housings, or Senix can custom build a packaged system according to customer requirements.

See our Display Accessories.

Wireless Connectivity to LAN or Cloud

AirWire Level Transmitter

With Senix AirWire® LoRa, tank level measurements are sent wirelessly from the tank to a receiver-gateway on your Local Area Network (LAN) and/or transferred to the cloud for worldwide access.

  • Transmit tank levels inside buildings without installing conduit or wiring
  • Collect nearby tank levels from up to miles away
  • No recurring cellular charges
  • No wiring is required at the tank site
  • Ideal for measurement rates as fast as a few times per hour
  • Connects with any Senix ToughSonic sensor with an RS-485 interface
