HFM200 Vortex Shedding Flowmeter is a new type stress detection vortex flowmeter, which adopts piezoelectric crystal as measuring element based on Karmann votex principle. It has lots of advantages such as wide range rate, high accuracy, small pressure losing, great medium versatility, with pulse signal output proportionate to flow, easy connection with computer. As the inspection probe is installed separately with vortex generator, and the heat-resisting piezoelectric crystal does not connect with medium, therefore the instrument has simple structure, great versatility and high stability features.
Vortex flowmeter is widely used in heating, gas supply, chemical industry,environmental protection, metallurgy, textile, steel, medicine, paper,
drainage and other factories and mining enterprises on superheated steam, saturated steam,compressed air and general gases (oxygen, nitrogen, hydrogen,natural gas, gas, etc.), water and liquids (e.g., water, gasoline, alcohol, benzene, etc.) measurement and control.·Clear LCD display screen, display instantaneous flow and cumulative flow respectively
·High-strength piezoelectric crystal, integrated structure, impact resistance
·Optional temperature compensation, pressure temperature, to meet more field services
·The circuit board is processed through ageing before delivery, and it is with the real flow calibration for whole machine , more suitable for field use.
·No external power supply is required. It adopts 3.6V lithium batter for power supply, which can continuously work more than two years, especially suitable for use in the field where the power supply is difficult to access.
