Precise data monitoring with the RTR-500 series
T & D Corporation presents a wireless data logging system adaptable to indi- vidual needs. Net- worked data logger systems simplify
procedures and allow error-free access to meas- ured data at any time, and from any location. T&D’s RTR-500 series is ideally suited to large areas, storage facilities for chilled and frozen food, and temperature management during the trans- portation of pharmaceuticals, food and precision equipment. They monitor temperature, humidity, mA, voltage, pulse, UV, illuminance and CO2 via WLAN, LAN, GSM or USB.
Furthermore, the free Cloud T&D WebStorage Service perfectly complements the RTR-500 series. It enables unlimited access to live data readings, recorded data, battery levels and radio signal strength, watchdog log, in easy-to-read graphs or tables. Several additional free apps and software applications also contribute to easy, all-round su- pervision and monitoring.

Preventing a Break-in – non-invasive flowmeters in hygienic applications
Katronic clamp-on, non-invasive ultrasonic flowmeters have been supplied to a major biomedical product manufacturer where cleanliness is paramount, making it difficult to cut into process pipelines, and have helped site engineers by significantly reducing project lead time and costs.
There are many processes where clean operation is imperative, for example foods, fine chemicals and biosciences. Clean-downs and changeovers can take a long time. Katronic channel partner and instrumentation specialists WE Instrumenta- tion found that one of their key customers
had a real issue gaining permission to install new flow measurement, with typically six months of investigation and effort before permission would be granted to break into site pipework to install new instruments.
Katronic’s Matt Bird visited site and demonstrated the equipment by quickly achieving a good flow measurement using a hand-held KATflow 200 portable flowmeter. One of the key advantages of Katronic equipment is the fact that the ultrasonic processing core of every meter in the range is the same, so a measurement made with a portable meter absolutely mimics the performance of a fixed flowmeter. Installation is also straightforward with Katronic’s unique Audible Positioning Assistant that guarantees accurate sensor positioning. Following the successful demo, an initial order of Katronic fixed systems was purchased, followed with further orders after the first batch had proved to be as successful as the demonstration.
Commenting, WE Instrumentation’s Martin Adams said, “We see this as a great result for both Katronic and WE Instrumentation and proves the important points that clamp-on flow is the only technology that can be retro-fitted and provides a solution where company policies make permission to break into pipes, possibly introducing contamination and disrupting production nearly impossible.”

other sensor is heated to a specific temperature above the reference. As the flow rate increases, heat gets taken away from the heated sensor. More power is then applied to the heated sensor to maintain the temperature difference. The relationship between power and mass flow rate is estab- lished during factory calibration.
The First choice for Energy Management Flow Applications In the energy management arena, the ability to better monitor combustion air, fuel gas flow and compressed air can help identify losses that over short periods of time can affect a plant’s profitability. The two key phrases when discussing instrumentation for the
aforementioned are “cost effective” and “return on investment.” Without question, any situation can be resolved if enough financial resources are thrown in its direction. The idea is to realize the benefit in the shortest time frame possible at the most reasonable cost. Thermal dispersion mass flow meters meet these criteria.
Thermal Dispersion Mass Flow Meter
Thermal mass flow meters are primarily used in air and gas flow measurement applications. The meters consist of a transmitter and probe with temperature sensors (RTDs) located in the pins at the bottom of the probe. The reference sensor measures the process temperature and the

Thermal mass flow used in air and gas flow measurement Combustion air flow measurement to a boiler is important to maintain a stoichiometric ratio with the amount of fuel being supplied. Too little air flow can result in incomplete combustion along with additional carbon monoxide or pollutants depending on the fuel being burned. On the other hand, too much air flow can cool the furnace and waste heat out of the stack. The repeatability of the air measurement is essential to obtaining the most efficient air-fuel ratio (AFR)difference.
Measuring fuel gas flow (natural gas or propane) usage to individual combustion sources compared to the output (steam/hot water) can help optimize boiler efficiency and better manage energy consumption. Knowing individual boiler performance may also assist in operating those offering the best efficiency. Lowering fuel consumption is one of the easiest methods to reduce cost and improve profits.
