Introduction of functions and characteristics of vortex flowmeter
Vortex flowmeter has the following characteristics: 1. Simple and firm structure, no movable parts, high reliability and reliable long-term operation.
Second, the installation is simple and the maintenance is very convenient.
Third, the detection sensor does not directly contact the measured medium, with stable performance and long service life.
4. The output is a pulse signal proportional to the flow rate, with no zero drift and high precision.
Five, the measurement range is wide, the range ratio can reach 1:10.
Six, the pressure loss is small, the operation cost is low, and it is more energy-saving.
Within a certain range of Reynolds number, the output signal frequency is not affected by the changes of fluid physical properties and components, and the instrument coefficient is only related to the shape and size of the vortex generator, there is no need to compensate when measuring the volume flow of fluid, and there is generally no need to re-calibrate the instrument coefficient after replacing accessories.
The application range is wide, and the flow rate of steam, gas and liquid can be measured. The verification period is two years.
LUGB vortex flow sensor has an inner diameter range of 25-300mm (Full tube type)
, KTLUI Type Plug-In vortex street flow sensor application diameter range is 350-1200mm (Plug-in)
, Full tube measuring liquid accuracy is 1%, measuring steam and gas accuracy is 1.
5%, plug-in liquid measurement accuracy is 2%, steam and gas measurement accuracy is 2. 5%, the measured medium temperature is-Natural 20 ~ 150 ℃ ,-
40 ~ 250 ℃, 100 ~ 350 ℃ (Tube only)
, The output signal is a three-wire voltage pulse, three-wire 4-20mA, two-wire system 4-20mA.
Function 1. The temperature and pressure compensation function is integrated in the watch body at the same time, which can measure the standard volume flow rate or standard mass flow rate of fluid.
2. Fully intelligent and digital circuit design can automatically compensate the measured fluid density or standard volume calculation.
3. The new digital filtering and correction function makes the flow measurement more accurate and reliable.
4. The battery-powered type can work continuously for more than two years without external power supply.
5. The new dot matrix Chinese character liquid crystal display is more convenient to use and operate.
