Performance characteristics

● Data collection and monitoring system
Establish a fast and convenient data transmission channel between the flowmeter and the computer in the management center using 4G and other networks, without being limited by geography, terrain, or distance. As long as there is power and signal coverage, data from on-site instruments can be collected.

Remote real-time data collection
Keep track of on-site operations at all times, with timely and fast information.

● Improve efficiency and reduce operating costs
Reduce manual meter reading hours by only verifying data on-site when necessary.

● Timely maintenance to reduce fault losses
Timely reflect the on-site working conditions, and set alarms for abnormal pressure, temperature, and flow conditions.

● Multi user
Support multiple users to view site traffic, total amount, temperature, pressure and other data through the Internet.

● Automatic data collection
The collection time and frequency can be changed according to the needs.

● Visual operation
The automatic collection of instrument data can change the collection time and frequency according to one's own requirements;


Provide historical data query and chart display; Printing data reports; Temperature and pressure self diagnosis and alarm output, providing instrument fault query; Real time display of online site and instrument data.

Technical Parameter

Power supply mode
  External power supply method: ZRC external DC 8-12V DC power supply.
  External power supply method: ZDC external AC 220V power supply.
  Internal battery power supply method: Equipped with a set of 7.2V lithium batteries. The whole machine has low power consumption, static power consumption<100 μ A, and rated power<100mW. When using the built-in battery, after the external power of the ZDC product is cut off, the backup battery is enabled and automatically switches to low-frequency upload mode. The battery can be used for 5 years.

● Input method

  RS485 communication, single channel. The remote transmitter and flow meter are wired (RS-485, one master and multiple slaves); The remote transmitter and server are wireless (TCP/IP, GPRS); Directly connect with secondary instruments such as waist wheel flow meters and turbine flow meters using RS485 to collect parameters such as total amount, flow rate, temperature, and pressure; Set the baud rate to 9600bps.

● Output mode

  4G wireless communication.

● Output power supply

  Under external power supply mode, output 12VDC, 50mA power supply.

● Environmental conditions

  Environmental temperature: -40 ℃ to+65 ℃.
  Relative humidity: 10% to 95%.
  Atmospheric pressure: 70kPa to 106kPa.

Explosion proof mark

  ZRC: Ex ia Ⅱ c T4 Ga, ZDC: Ex d Ⅱ b T6 Gb.

● Protection level

  IP65。

● Storage chip

  The built-in storage chip can store data once every 5 minutes for up to 8 years.

● Upload mode

  Support three reporting modes: proactive reporting, scheduled reporting, and interval reporting.

● Remote control

  Equipped with remote control and setting functions, the backend system can directly set parameters; Real time online remote monitoring achieved through external isolated safe DC power supply; Equipped with two data acquisition interfaces, both flow meter and controller data can be remotely transmitted.

● Alarm function

  High and low alarms can be set for parameters such as temperature, pressure, standard conditions, operating conditions, instantaneous standard conditions, instantaneous operating conditions, and internal battery voltage.

● Compliant with standards

  The surge protection performance meets the requirements of GB/T3482-2008 "Lightning Strike Test Method for Electronic Equipment", and can resist external interference such as conductive transient pulse group, static electricity, lightning surge, etc. Comply with the requirements of the "Management Regulations for the Production of Radio Transmission Equipment" and obtain model approval for radio transmission equipment.
