Smart gas Roots (waist wheel) flow meter Intelligent gas waist wheel (Roots) flowmeter is a new generation flowmeter that integrates flow, temperature, and pressure detection functions, and can automatically compensate for temperature and pressure. Gas is a compressible fluid, and its volume value is closely related to temperature and pressure. In order to unify standards for both parties, it is necessary to convert the actual volume into a standard volume under reference conditions (101.325 kPa 20°C). In order to achieve this purpose, the smart gas waist wheel flowmeter can accurately correct the volume of gas; it is an ideal instrument for gas measurement in urban gas, petroleum, chemical, electric power, metallurgy and other industries. more

$634/Principle：
The high frequency microwave pulse emitted by the guided wave radar travels along the detection module (cable or steel bar) and encounters the measured medium. Due to the dielectric constant mutation, the reflection is caused and part of the pulse energy is reflected back.The time interval between the emitted and reflected pulses is proportional to the distance between the measured medium.
Description：
Guided wave radar is a measuring instrument based on the principle of time travel. Radar waves move at the speed of light.The probe emits high frequency pulse and propagates along the cable or bar probe. When the pulse hits the material surface, it is reflected back to be received by the receiver in the instrument and transformed the distance signal into the level signal.
The reflected pulse signal is transmitted to the electronic circuit part of the instrument along the cable or pole probe.The correct identification of echo signal is completed by the pulse software. The distance D from the material surface is directly proportional to the time travel T of the pulse:
D=C×T/2
Where C is the speed of light
Since the distance E of the empty tank is known,
the level L is:
L=E-D
Set by input of empty tank height E (= zero), full
tank height F (= full range) and some
application parameters, the application
parameters will automatically adapt the
instrument to the measuring environment,
corresponding to 4-20ma output.
Measurement range:
Description：
H----Measurement range
L----Empty tank distance
B----Top blind area
E----Minimum distance from probe to tank wall
The blind spot on the top refers to the minimum distance between the highest material surface and the measuring reference point.
A blind spot at the bottom is a distance near the bottom of a cable that cannot be accurately measured.
There is a finite measurement distance between the top blind and the bottom blind.
Note:
Only when the material is between the
blind area at the top and the blind
area at the bottom, the reliable
measurement of the level in the tank
can be guaranteed.
Product introduction
3. Installation guide
Make sure the cable or bar does not touch the internal obstruction within the whole range. Therefore, avoid the facilities inside the tank, such as ladder, limit switch, heating equipment, support, etc.Note also that the cable or bar must not intersect the feed flow.
Note:the highest material level shall not enter the measurement blind area.The meter must be kept away from the tank wall.The instrument is mounted so that the cable or rod is oriented perpendicular to the surface of the medium under test.The instruments installed in the explosion-proof area must comply with the national regulations on the installation of explosion-proof dangerous area.The shell of benan type is made of aluminum.This instrument case is installed on the occasions where explosion protection is required and the instrument must be connected to the earth.
