The ASF7100 Series Swirl Flowmeter is a new type of gas flow meter which independently developed by ALIA. Using double sensors to achieve high accuracy and strong anti-interference. The structure is compact and no mechanical moving parts, with long service life. It adopts 16 Digit Microcomputer chip with high integration, small volume, good performance and excellent overall functions. It can detect flowrate, temp. and pressure, which also has automatic compensation function for temp., pressure and compressibility factor. ASF7100 Series Swirl Flowmeter can be widely used in petroleum, chemical, electricity, llurgy, coal and other industries.
ATF2000 Series thermal mass flow meter is designed on the basis of thermal dispersion. It adopts method of constant differential temperature to measuring gas flow. It has the advantages of small size, high digitization, easy installation and high accuracy. ATF2000 is a multi-functional thermal mass flow meter that measures mass flow and volume flow. With insertion type connection, the meter can achieve a hot-tapped installation and maintenance.
AWF400 series is a multi-jet wing dry type water meter. It features of accurate measurement, long service life and high repeatability, which is widely used in family, industry and agriculture and so on. With simple structures, the installation is convenient. It can directly read the totalzier, with optional RS485 output or reed switch pulse output.
AST420 Series Signal Converter is a device facilitates the conversion between analog signal an radio signal. It aims to convert 4-20 mA analog signal into radio signal to transmit the analog signal remotely without cable, which is widely used in the occasion of transmitting analog signals over long distances. Features Used in pairs, one for the transmitter and one for the receiver One device can transmit two analog signals, signal type 4-20 mA The distance can reach 600 meters and penetrate 3-4 walls indoors With waterproof case, can be used outdoors With ISM433M frequency band communication The transmitter can transmit the analog signal through the ratio while converting the signal to the analog output It has 64 independent channels and can run up to 64 pairs of converters and transmit up to 128 analog signals at the same time
APP300 is a portable programmer that is designed for APT3000 pressure transmitter, with 6-digit LCD to display current and internal parameters. It features button operation to correct APT3000 linear and 4-20 mA which is easy to use and reliable to run.
