1. Description of flowmeter composition system

Fischer porter has advanced vortex flowmeter in the world, which can be used to measure, detect and control the flow of various single-phase, uniform liquids, gases, high / low temperature superheated steam and saturated steam. It is widely used in industrial departments such as petroleum, chemical industry, metallurgy, electric power, papermaking, pharmaceutical, food and municipal construction, environmental protection engineering and other industries.

3. Technical characteristics of flowmeter

(1). Vt/vr series intelligent vortex flowmeter is intelligent:

● parameters (temperature, pressure, density, etc.) and instrument range and unit can be directly modified on site. The dial is equipped with data input keys, which can change data on site,

Data can also be modified through HART communication protocol (manual operator).

(2). Vt/vr series intelligent vortex flowmeter has excellent anti vibration performance:

● fischer&porter vortex street adopts four piezoelectric sensors for detection, the lower two are used to detect the flow signal of the medium, and the upper two are used to detect

External vibration (such as pipeline vibration) signals are input to the converter for compensation. This structure fundamentally eliminates the influence of external vibration. So that

The signal output is more stable, and the accuracy of the instrument is guaranteed

(3). Temperature and pressure compensation of vt/vr series intelligent vortex flowmeter:

● vt/vr converter can directly receive PT100 signal of temperature sensor, conduct temperature compensation, and output 4-20mA current signal; Or receive temperature sensor PT100 signal

And the pressure transmitter 4-20mA signal, conduct temperature and pressure compensation, output 4-20madc or RS485 signal, and display the compensated fluid flow.

(4). Vt/vr Series Intelligent Vortex Flowmeter adopts liquid crystal display, which can display the instantaneous flow, cumulative flow and various functional parameters of the medium.

(5). Vt/vr Series Intelligent Vortex Flowmeter modifies the instrument parameters as follows:

● it can be modified by three manual keys on site

● on site, it can be modified by manual operator through HART protocol

(6). Vt/vr series intelligent vortex flowmeter has high explosion-proof grade:

Intrinsically safe explosion proof: ex IA iict6

Flameproof: Exd II CT6

(7). Vt/vr series intelligent vortex flowmeter has high protection grade:

Protection grade: IP67

Protection grade: IP68 (diving type)

(8). Vt/vr series intelligent vortex flowmeter has complete materials

Various stainless steels: 0cr18ni9/316/316l, etc

Special materials: HC, Ti, etc

Others: it can be manufactured according to the needs of users

(9). Communication protocol:

HART-Protocol、RS485 Modbus
