KQ-TGF Digital Target Flow MeterDetailed product description：

1、 Overview:

1. Product types and applicable fields:
The KQ-TGF series digital target flowmeter is a new type of force induction target flowmeter developed based on the traditional target flowmeter measurement principle, fully utilizing its best characteristics, and combining new sensor technology and modern digital technology. It not only has the characteristics of traditional target, orifice plate, vortex street and other flowmeters without movable parts, but also has measurement accuracy comparable to volumetric flowmeters. In addition, its unique anti-interference, anti impurity performance, lightweight and reliable characteristics are widely used in various fields such as petroleum, chemical, energy, food, environmental protection, water conservancy, etc. From its effectiveness after use, the KQ-TGF flowmeter has extremely broad applicability, namely:
·Suitable for various pipe diameters, ranging from Φ 15 to Φ 2000mm to larger.
·Suitable for high and low temperature media: from -196 ℃ to+450 ℃.
·Suitable for high-pressure conditions: from 0 to 42Mpa (gauge pressure).

2. Characteristics of KQ-TGF digital target flowmeter:
·Can accurately measure the flow rate of liquids, gases, vapors, viscous media, and various fluid media under various normal temperature, high temperature, and low temperature conditions.
·Extremely high sensitivity, capable of measuring ultra-low flow rates, and can measure low flow velocities of 0.08m/s.
·No movable parts, safe and reliable to use.
·Accurate measurement, high precision, and total measurement can reach 0.2%.
·The measurement range is wide, with a maximum measurement range of 1:30.
·Good repeatability, generally 0.1-0.08%, fast measurement.
·The pressure loss is small, only about 1/2 △ P of the standard orifice plate.
·Dry calibration method can be used, namely the method of hanging the weight code.
·The target plate can be replaced according to actual needs to change the measurement flow range.
·It can directly read the displayed values online and also transmit and send messages.
·Easy to install and maintain.
