Professional flowrate instrucment and meter plant of bright cypress of Guangzhou, intellectual vapour flow-rate meter producer, vortex flow transducer
The vortex flow transducer does not have but moveable piece, simple in construction and firm, accuracy of measurements influence outside the characteristic temperature, pressure, density, degree of viscosity of medium within the range of specified Reynolds number, its intelligent two-wire system is exported, the on-the-spot display-type has its unique characteristics:
Adopt ultralow function that drunk god stock, consume the single chip microcomputer technology and adopt EEPROM to lose electric protection in accumulating the flowrate ' Time is greater than 10)
Not revised by the linear error the gauge factor by the software, has improved the metric precision of the complete machine. Bright cypress instrument Co., Ltd. market department of Guangzhou
And two kinds of battery-driven patterns of adopting on-the-spot 24VDC to supply power, have solved do not have (increase) lived The occasion of the direct current power supply needs to reveal or take a great difficult problem of standard image output users' live.
Application
Used in large, medium-sized, small various pipeline water supply and drainage, industry's circulating, sewage disposal extensively, oils, chemical reagent and compressed air, saturation and superheated steam, natural gas and measurement of different medium flowrate. The foot of vortex flow transducer of operating principle, according to & ldquo; The intersection of Karmen and the intersection of whirlpool and street & rdquo; A kind of fluid shaking instrument that the principle develops into, can show with the following formula:
In the type: f: Separate the frequency in swirl
St: Strouhal counts, refers to fig. (5)
v: Velocity of flow
d: The body width takes place in the swirl
K: Gauge factor: The total amount of pulse of separating in swirl and proportion of total amount of the volume
K: Gauge factor: The total amount of pulse of separating in swirl and proportion of total amount of the volume
( 1/3m3) ( 2)
In the type: K: Meter constant ( Pulse l/m3)
N: Pulse total number ( Time)
Q: Total amount ( m3) of the volume
Separate the relation such as formula ( 3) between frequency and fluid flow in swirl Shown
f = K· Q ( 3)
In the type: f: Frequency ( Time)
Q: Flowrate (m3/ h)
So separate the frequency to measure the fluidic flowrate of the pipeline through measuring the swirl. Refer to fig. ' Six)

Sensor unsuitable to used in great occasion of shaking etc., installation should try hard from the pump a little in order to avoid introducing the non- flowrate signal farther.
While needing to turn on the converter end cap live, must tighten the cover after finishing operating in case that the circuit board is made moist.
The sensor is when the medium is dirtier and includes more suspended substance, should pay attention to washing regularly, don't touch the bad sensory probe while paying attention to washing. Intellectual eddy meter Bright cypress instrument of compressed air, saturation and overheated steam meter
