Minimizing risk with meter exchange

Ensuring safety by modernizing ageing technology

Power plants are often-hazardous environments housing plenty of potential dangers – putting people and business at risk. Although plant operators uphold safety as a value, incidents continue, and in the case of damage or loss of production, costs arise. Any preventive measure is more cost-effective than a forced outage. Replacing mechanical meters and other outdated technologies with more reliable and efficient systems is key to ensuring maximum process safety and performance.

Reliable and efficient metering - in safe hands

Direct, accurate, cost-saving flow measurement

Direct, accurate flow measurement at the gas turbine inlet

Fuel consumption has a huge impact on a plant’s efficiency and bottom line making it essential to accurately measure natural gas flowrate. Traditional turbine flowmeters measure volume only, meaning other meters are needed to determine mass or corrected volume flowrate. Subject to wear, the accuracy of these meters drifts over time, and they require periodic greasing. Exchanging turbine flowmeters with the Promass Coriolis allows for the direct determination of gas mass flow.

  • Promass Coriolis is multivariable: no need for additional meters to measure and correct for pressure, temperature and density

  • Better accuracy of +/- 0.35% means large gas savings

  • Increased reliability and safety from Heartbeat in-situ verification and self-diagnostics

Higher sensitivity scintillator-style detector

Exchange the detector and keep your Gamma radiometric source

Several tough applications in fossil fuel, biomass, and Waste-to-Energy plants continue to rely on Gamma radiometric level, point level, and density measurement. But in typical installations with Geiger Müller tube receivers, measuring performance deteriorates over time due to declining source activity and the relative insensitivity of receivers. You can extend the lifetime of your existing radioactive source by switching to newer scintillator-style detectors.

  • Higher sensitivity detectors like the Gammapilot FMG60 function with low radiation fields allowing you to keep your existing source for many years to come

  • Avoid replacement and disposal costs, paperwork, and reduce risk

Automatic cleaning and calibration

Automatic, low maintenance pH monitoring in desulfurization

Control of the pH value is very important for a properly functioning flue gas cleaning system. But the tough, abrasive conditions in the gas scrubber make life very difficult for pH sensors. Standard installations require frequent cleaning and manual calibration, and regular sensor replacement. Thankfully, smart systems can now automate the cleaning and calibration of sensors to ensure reliable, consistently precise pH measurement, and reduced maintenance costs.

  • Fully automatic cleaning and calibration with Liquiline Control CDC90 pH measuring system

  • Ensures reliable measured values, longer service life for pH sensors, and lower maintenance costs

  • Better working safety by minimizing maintenance work in hazardous environments

Density and flow measurement in flue gas desulfurization (FGD)

Slurry density measurement in flue gas desulfurization (FGD)

Lime slurry density measurement at the injection site is important for the efficiency of the flue gas cleaning process. Once a certain concentration is achieved the gypsum is removed from the process. Density measurement can be done with the sensitive and safe radiometric Gammapilot. For customers who prefer not to use radiometric measurement, a new technology Promass Coriolis can simultaneously measure density, mass flow, and temperature.

  • New generation radiometric Gammapilot is sensitive, safe, and robust to ensure the highest possible measurement availability

  • Promass Coriolis can remove a nuclear source from your plant, reducing certification, paperwork, and training concerns

Next-generation tablet PC

Next-gen tablet PC replaces HART® Handheld Communicator

Device configuration is a big part of the everyday work of a maintenance engineer. Most handhelds, are limited to a single protocol (e.g. HART) and limited to configuration only. Boost field productivity and safety with the rugged new tablet PC Field Xpert that brings powerful and streamlined management of all instruments to your fingertips. Save time and cost in tough environments with easy device configuration and verification, and enhanced connectivity.

  • Save time with the simple to use, touch-optimized modern user experience

  • Reduce cost using a single device for PROFIBUS, Modbus and Endress+Hauser-specific service interfaces. One-click, fast connection to devices thanks to automatic hardware detection

  • Improve compliance: create configuration and Heartbeat verification reports, show the echo curve and more

Capacitance level measurement of fly ash hoppers in Electrostatic Precipitators & Filter Bag Houses

Measure fly ash level without nuclear source and receiver

Removal of particulates from stack gases requires point-level switches to indicate when fly ash hoppers in Electrostatic Precipitators (ESPs) and Filter Bag Houses are full. Radiometric (Gamma) measurement is a well-recognized reliable solution for this, especially with poorer quality coals. Customers who prefer not to use radiometric measurement can exchange to capacitance point level switches like the Solicap FTI77.

  • Remove a nuclear source from your plant, reducing regulatory burden, paperwork, and training concerns. Lower cost of maintenance

  • The most robust and reliable capacitance sensor available today, Solicap FTI77 is perfectly suited to hot and abrasive environments

  • Large active area provides very stable measurement (no false trips)
