I. General

1) Types of products and applicable domain:

HGTF seriestarget flowmeter with digital display is a completely new force inductiontarget flowmeter developed based on measurement principle of traditional targetflowmeter, making full use of most excellent features of the same, and incombination with new transducer technology and modern digital technology. Thisproduct not only features the characteristic of no movable part as intraditional flowmeters such as target flowmeter, orifice flowmeter and vortexflowmeter, but also a measurement accuracy matching that of volumetricflowmeter. In addition, this product has the performance against interferenceand impurities, and is light and reliable, hence is widely used in petroleumindustry, chemical engineering, energy industry, food industry, environmentalprotection and water conservancy etc. In terms of operation effect, HGTFflowmeter has extremely wide applicability, i.e.:

· applicableto various pipe diameters: from Φ15 to Φ2000mm and larger;

· applicableto high and low temperature media: from -196℃to +450℃;

· applicableto high pressure operating conditions: from 0 to 42Mpa (gauge).

2) Product features:

· accuratemeasurement of flow of fluid media such as liquid, gas, steam and viscous mediaetc. under various normal temperature, high temperature and low temperatureoperating conditions;

· extremelyhigh sensitivity capable of measurement of ultra small flow (minimum flow thatcan be measured is 0.08m/s;

· no movablepart, hence high safety and reliability;

· highmeasurement accuracy and precision (reaching 0.2% for measurement of totalquantity);

· widemeasurement range (reaching 1:30);

· good repeatability(normally 0.1～0.08%) and fast measurement;

· smallpressure loss, only about 1/2△P of standard orifice;

· drycalibration can be used, i.e. poise hanging method;

· targetplate can be replaced as required to change flow measurement range;

· capable ofonline direct reading and remote transmission/signaling;

· easyinstallation and very easy maintenance.
