| Description
DY Vortex-in-one flow sensor is a new flow sensor using
international advanced technology which is widely used in fluid
measurement of thermal power, petroleum, chemical industry,
metallurgy, paper making industries. This flow meter has no
movable parts, so it is stronge reliability, high accuracy, long
life and may measure accurately instantaneous flow and cumulative
flow of fluid in a very wide flow range. It is not affected by
temperature, pressure, viscosity and composition of medium, at the
same time, it is not blocking, not cards, not easy to scaling,
high-temperature and high pressure resistance, safety and
explosion-proof, and suitable for harsh environment.

function
pulse output function
Targeted pulse, nontargeted pulse, the maximum pulse
frequency is 10KHZ
self-diagnostic and alarm output
If it alarms (super-range output signal, EEPROM errors,
vibration noise, blocking, bubble and other abnormal state),
signals will be output and displayed.
status output function
If flow is lower than seting flow, a status signal will be output.
In addition, there is also loss of electric data protection,
nstrument error compensation, hardware fault output and other
functions. |
