Standard serial communication interfaces: RS-485 and RS-232C;
Standard Modbus communication protocol. In addition to supporting our company's ScanX data management software, it also supports popular professional configuration software such as iFIX, Kingview, MCGS, etc., without the need for dedicated drivers;
Can be connected to an external micro printer, supporting manual printing and timed automatic printing, meeting the needs of users for on-site printing;
Integrated hardware real-time clock, the clock can run accurately even in the event of power failure;
The new switch power supply operates normally within the range of 85VAC-256VAC;
Provide transmitter+24VDC isolated power distribution.
The compensation model is rich and can compensate for various media such as liquids, general gases, and steam.
The small flow supplement metering function compensates according to the set value after the instrument loses power.
Provide 8-hour shift, 12 hour shift reports, daily reports, and monthly reports. The settlement time can be freely set.
When the temperature sensor malfunctions, it will automatically switch to the set temperature and calculate the compensation amount based on the pressure.
It has a power-off recording function, which records the time of instrument power on and power-off, displays the cumulative power-off time, and prevents users from stealing steam during power outages.
The all aluminum sealed shell and internal shielding plate ensure the normal operation of the instrument in harsh environments.
