The Atlanta Instruments range of ultrasonic flowmeters incorporate some of the latest high speed DSP technology. The new flowmeters, provided with a rich variety of sensors and support diverse applications of flow measurements. The company's single channel (Version 8.xx) series ultrasonic flow meter has been manufactured with patent technologies and is equipped with more functions and advanced performance than the previous versions.
The Version 8.xx series ultrasonic flowmeter has been upgraded based on the Version 7.xx series ultrasonic flowmeter, which is still the main product line of the company. The new Version 8.xx retains most of the features and functions of the previous versions: the pulse measurement technology, the ultrasonic igniting and the small signal receiving circuits. The main improvements are made on the battery supply circuit and on the transmitting circuits. All other circuits are simply integrated into this new version without major modifications, due to the fact that some of the most advanced measurement technologies have already been applied and a more reliable model of ultrasonic flowmeter attained.
The series of flowmeters incorporate the latest ICs manufactured from the famous semiconductor manufacturers like Philips, Maxim, TI, Winbond, and Xilinx. The hardware features the ease of operation, high accuracy and reliability, while the software provides a very user friendly interface and many more functions. It employs a patent balanced lower voltage multipulse igniting circuit which increases the anti-interference ability magnificently so that the flowmeter will work properly even in demanding industrial environments such as those with a power frequency transverter working nearby. Other features are the signal receiving circuits feature self-adapting performance so as to ensure that the user can easily operate the instrument without any adjustment.
The main features are: an accuracy of up to 0,5%, linearity of 0,5%, 0,2% repeatability, ±32 m/s velocity, built in datalogger and can measure pipe sizes from 20 to 6000 mm. It uses some of the most advanced direct time measuring methods; the meter offers a signal resolution of 0,2 ns. In addition it runs out of a regular power supply (110 V/220 V), built in battery or 24 V d.c. supply. Signal outputs include current signal, frequency signal, serial data and switch outputs (one OCT and one relay output). HyperTerminal can be used to dump the datalogger data from the flowmeter. All the outputs displayed on the unit can be transmitted to a PC via RS232 for further processing or storage. GPRS or CDMA (3G) selected configuration modems have also been added to the range that directly communicate with the main board. This feature is an option to the flowmeter series and needs to be specified on order. Another option is the explosion-proof type.
The selection for standard type materials like; carbon steel, stainless steel, cast iron, ductile iron, copper, PVC, aluminium, asbestos and fibreglass can be made via on-board keyboard selection. The many different liner materials and fluid types can also be selected that way. These flowmeters are designed to measure fluids like water, seawater kerosene, gasoline, fuel oil, crude oil, propane at
45°C, butane at 0°C, diesel oil, caster oil, peanut oil, 90 octane petrol, 93 octane petrol, alcohol, hot water at 125°C and other liquids. The four selectable transducer mountings are the so called V-method, Z-method, N-method and W-method. Lower flow cut-off feature was incorporated to avoid invalid accumulation. All these features are protected by value modification lockouts via the keyboard.
The most exciting of all is the new dual channel (two paths) and quad channel (four paths) flowmeter system that has been added to the product range. Atlanta Instruments has been selected to be the sole agency for these dual and quad path flowmeter systems. It will soon introduce the same brand radar level transmitter to its products range.
Atlanta Instruments' range of flowmeters will soon be available for companies interested in being distributors.
