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.

  • 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

A New Twist on Old Magnetic Flow Meter Technology

FPI Mag Meter
FPI Mag Meter
The McCrometer FPI Mag employs a ground breaking configuration. Unlike full-bore mags, the FPI Mag is placed in the middle of the flow stream where an array of coils and electrodes measure at numerous points spanning the diameter of the pipe.

The FPI Mag's accuracy rivals that of conventional mag meters, so there's no compromise on performance. Save up to forty-five percent on installation and total cost of ownership. The FPI Mag is the only flow meter of its kind that eliminates the need for heavy equipment and excessive manpower necessary to support installation. Installing an FPI Mag is easy -  there's no need to shut down or drain the lines. The FPI Mag even fits in compact spaces with limited access points. Prep for conventional mag meter installation requires heavy equipment and draining lines. Conventional mag meter installation is costly complicated and time-consuming.

Benefits of using the McCrometer FPI Mag Meter:
  • Save up to 45% on installation and total cost of ownership
  • No downtime servicing or replacing the FPI Mag Meter
  • Over $5000 savings
  • 6 hours of labor saved

In Situ Microbial Fermentation Analysis and Mammalian Cell Culture Analysis - for R&D and Mass Production

Biopharmaceutical production processes, including microbial fermentation and mammalian cell culture vary greatly with organisms behaving differently and metabolizing at varying rates. With in-process measurements you can monitor the key parameters and optimize the fermentation or cell culture processes. Using a bioprocess analyzer allows for rapid analysis of many different properties with one quick measurement.

Both Fermentation and Cell Culture processes in a single, closed vessel can benefit greatly from in-process or in situ chemical analysis. Whether you are working with small laboratory scale reactors or large scale production equipment, Near Infrared (NIR) analysis can make your processes more efficient and optimized. NIR provides useful analysis for R&D, Scale-up, Process Development and full-scale production. Large-scale fermenters and bioreactors can hold as many as 250,000 gallons of raw material, which may be in process for hours or several weeks. An NIR analyzer can monitor both the start up media and emerging product on-line, despite the thick, soupy nature of the material.

Additionally you can get online measurements of Glucose, Glutamate, Acetate, Lactate, Ammonia,
Cell Density, Product Titer/Protein with NIR analyzers. These properties can be measured In-Situ or in the lab. If you have many fermentors/reaction vessels,  optical multiplexers will allow one analyzer to monitor up to 20 measurement points, sending all the valuable data to your process control system automatically.

In mass production the electrical power savings alone can provide payback for an NIR analyzer within a few months. Added product yield from improved process control also generates enormous payback, as well as reducing the occurrences of lost batches.
