Gas Electronic Flowmeter Flow Meter Electromagnetic for City
1). Explosion-proof design accords with the national
explosion-proof technology requirements and has
been approved by tests and can be used in various explosion-proof
2). It,s high resistance, fast response design can make undistorted
collection of weak signal and fast
response to the flow changes. Its range rate can reach 100:1.
3). It has the function of low conductivity measurement.
4). It has the consistency of converter’s interchange, which can
avoid input parameters repeatedly.
5). Wide range of power supply mode is available (DC: 18V-36V/AC:
6). It is the first domestic company that adopts the function of
saving settings before delivery, which can
avoid the loss of the parameters.
7). It adopts the international leading excitation technology,
which circuit is simple, stable, and reliable.
8). It has the function of infrared remote control and button
operation so as to make the operation more
9). It provides the function of zero correction of sensor and
automatic zero adjustment.
10). It has multi-language interface to satisfy all the users’
11). It has the function of self-adjustment and self-checking.
12). It has lightning-protection and electricity-protection
circuits. The effective, anti-interference circuits apply to all
kinds of bad environment.
13). A variety of output communication interfaces are optional.
HART communication (optional);RS485 (Modbus is optional)
Profibus (optional)16-figure current loop4~20mA output 0-10kHz
frequency output Pulse equivalent output
The series of Vortex Flowmeter is based on Von Karman’s Vortex
Principle, which adopts piezoelectric crystal as testing
components. It is a new kind of stress detecting vortex flow
meter.It has the advantages of wide range rate, high accuracy,low
pressure loss, good medium generality, pulse signal output
proportional to flow, convenient to connect with computer etc.As
the detector probe of sensor and the vortex generating body are
installed separately, and the high temperature resistant
piezoelectric crystal does’t contact with medium, so the instrument
is of simple structure, good generality, and high stability.
