Kaidi KD FVT Pipeline Vortex Flow Meter ExiaIICT5 or ExdIIBT6 for oil and chemical reagents
F V T type vortex flow meter is a volume flow meter that measures the volume flow of gas, steam or liquid, the volume flow rate or mass flow rate of standard conditions according to the Karman vortex street principle. The instrument uses advanced differential technology, with isolation, shielding, filtering and other measures to overcome the problems of poor shock resistance and small signal data disorder of similar products, and adopts unique sensor packaging technology and protective measures to ensure product reliability .
①No moving parts, long-term stability, simple structure, easy to install and maintain
②The output of the sensor is pulse frequency, its frequency is linear with the actual flow of the fluid being measured, the zero point has no drift, the performance is very stable, and the structure is diverse, including pipeline and plug-in flow sensors.
③High accuracy, usually the measurement accuracy of liquid is ±1.0%; the measurement accuracy of gas is ±1.5%
④Flexible installation method, according to different process pipelines on site, it can be installed horizontally, vertically and inclinedly at different angles
⑤The use of noise-cancelling electric circuit and anti-vibration sensor head has certain anti-environmental vibration performance
⑥Using ultra-low power consumption single-chip microcomputer technology, one 3V10AH lithium battery can be used for more than 5 years
⑦The non-linearity of the meter coefficient is corrected by the software to improve the measurement accuracy
⑧EEPROM is used to protect the accumulated flow from power down, and the protection time is more than 10 years
This instrument can be widely used in large, medium and small pipeline water supply and drainage, industrial circulation, sewage treatment, oil and chemical reagents, compressed air, saturated and superheated steam, natural gas and various medium flow measurement.
