The changing condition of fluid level,
pressure and temperature is transmitted to a monitoring center
through a wireless system for real-time monitor. the monitoring
center stores, groups, analyses various incoming data. the
monitoring center can send warming signal according to preset alarm
threshold, this will provide a basic data for subsequent control
and corresponding decision-making. as one of famous companies in
sensor industry.
Xi'an Chinastar M&C Ltd has released two
types of wireless sensing system based on Zigbee for short distance
coverage and GPRS for network transmission for level depth,
pressure and temperature monitor.
For the zigbee based system is suitable for
short distance or more centralized occasions, can be widely used in
fluid level in coal mine, city drain control, industrial waste
water level control, building water pressure control.
etc.
For the GPRS based system is applicable to
level monitoring of rivers and lakes, city water supply pressure
control, etc.
