Non-invasive, Ultrasonic Flowmeters Are Clear Winners in Wastewater Pumping Stations

Pumping stations are an integral part of each wastewater network. Flow measurement at such stations is critical as the quantities which are fed to the treatment plant have to be monitored.

Conventionally, magnetic inductive flowmeters are used for such measurement tasks. However, due the medium, which is heavily charged with solid matter, these instruments are subject to wear, leading to incorrect readings and subsequent failure.

Non-invasive ultrasonic flow meters prove to be the better measuring solution. Since these meters measure from outside the pipe wall, there is no wear and tear on the meter making them virtually maintenance-free. Furthermore, there is no need to open the pipe for installation, which would result in at least a partial interruption of operation. There isn't a need for multiple workers or heavy equipment for installation. The entire measuring system, consisting of ultrasonic transducers and a measuring transmitter, is easily carried to the measuring location and installed by a single person. There is no disconnection of pipes or flanged joints, unlike when installing a magmeter. Finally, there is no need for block valves to hold back flow during installation, repair, or replacement.

Advantages:
  • Reliable and accurate non-invasive wastewater flow measurement without any wear and tear or measurement drift
  • Extremely easy to set up a measuring point without any impairment of the plant’s normal operation
  • ATEX-certified transducers with protection degree IP68 for use in hazardous areas as well as in flooded chambers

Campus Metering: Improve the Energy Efficiency of Your Building with Clamp-on Flowmeters

Today there are many reasons to focus on energy optimization efforts. Due to rising cost of fossil fuels and environmental concerns, decreasing overall energy consumption, decreasing operational costs, improving HVAC performance, improving building quality and certification rating is becoming increasingly important. Facility Managers are stepping up their efforts to find efficiency and savings related to heating, ventilation and air conditioning systems, including chillers, boilers, and air-handling components. Energy-efficiency is a top priority for institutional and commercial organizations and will continue to grow in importance for the foreseeable future.

Finding new ways to reduce energy consumption in buildings without compromising comfort and indoor air quality is an ongoing challenge. One of the most significant options a facility has is to add BTU energy metering that is able to accurately meter the new performance of upgraded chillers, pumps, and chilled water distribution system.

Superior precision can be achieved by using clamp-on flowmeters with specially matched and paired ultrasonic transducers and temperature probes that control the heating and cooling flows within the building. These devices offer a superior solution with a high degree of reliability and repeatability for both temporary and permanent applications.

The biggest challenge in retro-fitting flowmeters in existing piping structures are the very tight piping typical of chiller plants, existing valves, vents, and pipe bends. Clamp-on ultrasonic flowmeters provide an easy work-around. Since the clamp-on ultrasonic transducers are simply mounted on the outside of the pipeline, plant operation is not affected in any way during retrofitting. The reworking of existing piping systems for flowmeter installation is not required, making the clamp-on flow meters an ideal solution for retrofitting existing facilities.

Designed with temperature compensation to eliminate inaccuracies or drift through deviations, and powerful correction algorithms to compensate for non-ideal pipe conditions, these energy flow meters offer an accuracy of 1% or better on the flow rate. Plus, low flow velocities can be detected reliably and accurately.

The advantages for choosing clamp-on ultrasonic flowmeters for HVAC retrofit are:

  • Reliable, non-invasive recording of thermal energy (BTU) flows
  • Practically wear-free measurement without measurement drift, unaffected by potential coating formations
  • Works independently of the conductivity of the medium
  • Simple set-up of measuring points without any interruption of operation
  • Minimum installation effort
  • Compact measurement system, can also be easily installed on measuring points which are difficult to access

Research demonstrates the addition and/or upgrade of metering existing HVAC systems can offer effective solutions for energy conservation and thermal comfort, with possible energy savings in the range of 30-40%.
