qualification: P-101.325kPa, T=293.15K (also could take 273.15K as 0°Cstatus according to requirement)
Service condition:
Ambient temperature:-30°C~+50°C medium temperature: 20°C ~+80°C
Relative humidity: 5%~95% Atmospheric pressure: 86KPa~106KPa
The pressure loss of flowmeter: gas pressure loss shown in the above table, liquid remains undetermined
Electric performance indexes:
a. Operating power supply
Inner power supply: a 3.6V lithium battery, the screendisplays the battery capability in real time, the battery voltage within 2.9~3.6V could operate normally; when the voltage is lower than 2.9V, appears voltage shortage indication
External power supply: +24VCD±5%, ripple ≤±5%, when connecting external power supply, inner power supply cuts off automatically, and the whole machine operates with exterior power supply.
b. Output manner (Require additional power +24V)
Pulse signal of operating condition (three-wire system): Amplify and output the pulse signal of operating condition detected by flowmeter sensor, up level≥20W, low level≤1V, transmission distance≤300m.
4~20mA standard analog amount signal: 4~20mA standard analog amount signal line is in correspondence with 0~Qmax (standard flow), flow range is set by instrument, transmission distance ≤300m, power supplier is +24VDC exterior power.
RS485 interface signal: networking with the up-machine directly could transmit detected temperature, pressure, instant flow, standard volume flow and relevant instrument parameters, etc. And by matching with special MODEM could carry out telephone communication.
The entire machine consumption:
The function of real time data storage:
In order to adapt to the requirements in data management, the real-time data storage function is added, including:
Above storage data could be read and fetched by using a laptop PC or desktop computer through RS485 interface, analyzing according to the user formed data statement and curve figure.
The pressure loss of flowmeter
P =Po. p/1.205
In this formula: P---the actual pressure loss of flowmeter (kPa)
p----The medium density under actual condition (kg/m2 )
Po--- The pressure loss when the medium is dry air under standard condition (kPa)
