PROCESS INDUSTRY (LIQUID LEVEL) APPLICATIONS

In the process industry, challenges are diverse and demanding:

  • High accuracy requirements for continuous, real-time measurement in storage and process tanks
  • Variety of liquids with different viscosities, densities, and surface conditions, including foam and turbulence
  • Harsh operating environments, from solvent extraction tanks to high-temperature industrial fluids
  • Compliance with strict industry standards such as ATEX, IECEx, CE, and 3-A sanitary certification
  • Integration flexibility, with outputs from analog to digital fieldbus and Ethernet protocols
  • Installation constraints, including single-port access for multi-parameter measurements
  • Long measurement ranges, up to several meters, without sacrificing precision

Our Level Plus® portfolio of magnetostrictive liquid level transmitters, with Temposonics® Technology, is designed to excel in every scenario. From hygienic designs for food, beverage, and pharmaceutical applications to explosion-proof models for oil, gas, and chemical industries, our sensors offer accuracy, reliability, and flexibility - backed by global support and trusted certifications.

At Temposonics, we understand these challenges because we’ve been solving them for over 50 years.
Explore how our level transmitters deliver reliable results in a variety of liquid level applications:

AST tank gauging

Key industry challenges:

Measuring product level, interface, temperature, and volume in large above-ground tanks - often with just one mounting point - can require multiple instruments, increasing cost and complexity.

Temposonics’ solution:

The Level Plus Tank SLAYER® provides a 4-in-1 measurement (level, interface, temperature, volume) from a single opening.
It uses a user-uploaded strap table (up to 200 points) and requires no scheduled maintenance or recalibration.

Benefits:

  • Lower installation and lifetime costs compared to radar or servo gauges
  • Simplified tank modification and easier retrofitting
  • Reliable, accurate inventory control with minimal downtime

Level monitoring of liquid gas

Key industry challenges:

Measuring both product level and temperature in LPG bullet tanks typically requires multiple sensors or access points, which increases cost, installation complexity, and downtime. Servicing conventional equipment often demands tank entry, leading to extended maintenance interruptions and safety risks.

Temposonics’ solution:

The Level Plus RefineME® transmitter provides dual measurement - product level and temperature - through a single process opening. It fits into a standard 2-inch process connection, with all electronics fully serviceable from outside the tank, eliminating the need for tank entry.

Benefits:

  • Enhanced safety and reduced operator exposure
  • Less downtime thanks to easy, external servicing
  • Lower installation and maintenance costs: Multifunction output from a single sensor reduces hardware and complexity

Chemical blending tanks

Key industry challenges:

Liquid level measurement in harsh process environments is often affected by steam, foam, vapors, mixing, and fluctuations in the dielectric constant of the liquid. These changing conditions can cause instability, signal loss, or inaccurate readings with many conventional sensing technologies.

Temposonics’solutions:

Level Plus® liquid level transmitters using magnetostrictive technology are inherently resistant to these environmental challenges. The RefineME® model delivers steady, accurate measurement regardless of steam, foam, or vapor presence and adapts to changes in dielectric constant. It also supports HART® communication for easy programming and calibration without interrupting operation.

Benefits:

  • Consistent accuracy in fluctuating process conditions
  • Improved process reliability by eliminating measurement instability
  • Simplified setup and maintenance with HART®-enabled remote configuration
  • Reduced downtime.

Inventory monitor of spirits

Key industry challenges:

Distilleries require highly accurate inventory monitoring to track how much alcohol is being produced or consumed. Since alcohol production is taxed based on volume, measurement inaccuracies can lead to overpayment in taxes. Additionally, distilleries operate in hazardous environments due to the flammability of alcohol, requiring equipment that meets strict safety certifications.

Temposonics’solutions:

The Tank SLAYER® liquid level transmitter delivers exceptional measurement accuracy, ensuring precise volume tracking for production and taxation purposes. It is certified with both intrinsically safe and explosion-proof/flameproof ratings, making it suitable for hazardous locations in compliance with safety regulations.

Benefits:

  • Reduced operational risk by using a certified, high-performance measurement solution
  • Reliable, consistent readings for production planning and quality control
  • Tax savings through precise inventory measurement, avoiding overpayment

Level measurement through foam

Key industry Challenges:

Accurate level sensing beneath foam layers - such as in brewing or fermenting tanks - is difficult using conventional technologies.

Temposonics’ solution:

Magnetostrictive technology can reliably measure fluid level under foam.
The SoClean® transmitter comes with sanitary finishes (Ra 25 µin or electropolished Ra 15 µin) and
meets 3-A hygienic standards.

Benefits:

  • Reliable level control in brewing and fermentation processes
  • Easy cleaning and compliance with sanitary regulations
  • Reduced foam-related errors or sensor fouling

Pharmaceutical production tanks

Key industry Challenges:

Pharmaceutical tanks require high accuracy with components that withstand washdown, sterile conditions, and clean-in-place (CIP) or steam-in-place (SIP) procedures.

Temposonics’ solution:

The SoClean® level transmitter provides an analog output for the tank level and is available in a sanitary Ra 25 µin finish or an electropolished Ra 15 µin finish. The complete stainless steel construction allows the SoClean® to be used in CIP, SIP, and washdown applications..

Benefits:

  • Meets strict sanitary and hygienic requirements
  • Low-maintenance design that withstands routine cleaning
  • Precise, reliable level control for batch and continuous pharma processes

Sanitary applications

Key industry challenges:

Bioreactors and blending tanks in the pharmaceutical industry typically require high accuracy with components that withstand washdown, sterile conditions, and clean-in-place (CIP) or steam-in-place (SIP) procedures.

Temposonics’ solution:

Level Plus transmitters are available with 316 (1.4404) stainless steel pipes and housings. The chemical compatibility of stainless steel allows the transmitter to be washed with caustic chemicals without compromising performance or longevity.
