overview

Capacitive target flowmeter is a new type of capacitive force induction flowmeter developed on the basis of traditional target flowmeter with the development of new sensors and microelectronics technology. It has the characteristics of no movable parts such as orifice plate and vortex street flowmeter, as well as high sensitivity, accuracy comparable to volumetric flowmeter, and wide range. The adoption of chip level capacitive force sensors and efficient anti overload structural design are the key cores for this new product to truly achieve high precision and stability. In addition to its unique anti-interference and anti impurity performance, it can replace the flow measurement problems that can be measured by conventional flow, especially in difficult flow measurement conditions such as high viscosity, dirty media, easy coagulation and blockage, high temperature, low temperature, strong corrosion, etc. It has good adaptability and is widely used in the fields of petroleum, chemical, metallurgy, power, pharmaceuticals, environmental protection, food, etc.

Wide range of applicable pipe diameters: Φ 10~Φ 2000 to larger;

Wide applicable temperature range:- 200°C ～700°C；

Applicable pressure conditions: 0-42MPa;

Suitable for various media: gases, liquids (including high viscosity liquids, slurries), steam;

Suitable for low velocity media, it can measure a minimum flow velocity of 0.08m/s.

Product Features

The entire instrument structure is sturdy and has no movable parts, making it easy to disassemble;

Multiple anti-corrosion and high/low temperature resistant materials can be selected (such as Hastelloy, titanium, etc.);

The whole machine can be made fully sealed without dead corners (welded form), without any leakage points, and can withstand high pressure of 42MPa;

The pressure loss is small, only about 1/2 △ P of the standard orifice plate;

Strong anti-interference and anti impurity ability;

The instrument is equipped with a self checking program, and the fault symptoms are clear at a glance;

The sensor does not come into contact with the measured medium, there is no wear on the components, and it is safe and reliable to use;

The dry calibration method can be used on-site, that is, the weight hanging method can be used, and single key operation can complete the calibration;

There are multiple installation methods to choose from, such as online plug-in, which has low installation costs;

Equipped with integrated temperature and pressure compensation, directly output quality or standard square;

It has optional small signal removal, non-linear correction, and selectable filtering time;

Capable of accurately measuring gas and liquid flow rates under various working conditions of room temperature, high temperature of 500 degrees, and low temperature of -200 degrees;

Accurate measurement, with an accuracy of up to 0.2%;

Good repeatability, generally ranging from 0.05% to 0.08%, and fast measurement;

The range can be changed by replacing the blocking element (target) according to actual needs;

Low power battery on-site display, capable of online direct reading of readings, and the display screen can simultaneously read instantaneous and cumulative flow rates as well as percentage bar charts;

Easy to install and maintain;

Multiple output forms, capable of transmitting various parameters remotely;

Strong shock resistance, capable of measuring pulsating flow within a certain range.
