MTKZ series IC card intelligent flow controller is a mechatronics intelligent IC card flow control instrument developed by Romette (Shanghai) Automation Instrument Co., Ltd. according to market demand. The product adopts advanced single-chip computer, imported integrated circuits and CPU card, with automatic billing, accurate and reliable, perfect performance, reasonable structure and other characteristics. The control system adopts micro-power design, lithium battery power supply, LCD display and data preservation. It can record the cumulative gas consumption of users and the cumulative gas consumption of each month. The product has a variety of protection prompt functions, which ensures the safety and reliability of the system operation. It can be equipped with various forms of flowmeters (ultrasound, waist wheel, turbine, spin-in). Vortex flowmeter, membrane gas meter and reserved connectors are designed, which can be connected with the remote monitoring system designed and manufactured by our company to meet the user's requirements for flow meter automation and pre-charge management.
1: can realize pre charge, automatic charging and accurate metering.
2: The control part uses advanced single-chip computer and imported integrated circuit in the world. The single-chip computer has high reliability, many I/O interfaces and large storage capacity. It is suitable for IC card industrial controller.
3: IC card adopts CPU card and ESAM module recommended by the Ministry of Construction to realize multi-layer key management, which lays a good foundation for the security, confidentiality, reliability and multi-use of system data.
4: large screen LCD display, intuitive display of various data and status.
5: Select large capacity lithium batteries, high performance micro-power circuit design, prolong battery life, powerful software functions, superior performance.
The 6: control system is designed to detect battery power. When the battery power is insufficient, the system prompts "low power" and alarms the user to replace the battery; when the battery power is exhausted, the valve closes and the battery must be replaced before the system can resume normal operation.
7: Reserve communication interface, which can record the gas consumption and alarm parameters, and transmit the data to gas company through RTU, so as to facilitate the analysis and statistics of users'gas consumption. The remote monitoring of the controller is realized.
8: When matching with flowmeter connection, the standard volume corresponding to unit pulse can be set to meet the different requirements of users.
9: the largest gas consumption can be achieved at 99999999m.
10: when the valve is not successful, zero air volume is measured in a negative direction, and automatically deducted at the next time when the gas is purchased.
11: Advanced management software, friendly user interface, support WIN2000/XP/NT system, support network functions.
The 12: system can issue user cards, open valve cards, test cards, time cards and other cards to facilitate the use and management.
The 13: management system has the functions of automatic identification, replacement of cards and replacement of tables, so as to ensure fairness and rationality.
14: products have many kinds of security protection functions to ensure the safety and reliability of the system.
1. Low power protection function of base cell.
2. Broken line protection function.
3. Electromagnetic interference protection function.
4. Audible and visual alarm function.

1:Before installing , the dirt in the pipeline must be cleaned up so as to prevent damage to the controller.
2: Intelligent controller is flanged connection, usually installed horizontally. Flowmeters with special requirements in front and back straight pipe sections should be installed and connected according to the installation requirements of flowmeters.
3: The direction of gas flow should be the same as the direction indicated on the shell of the controller. The axis of the controller should coincide with the axis of the pipeline during installation, and the sealing gasket should not protrude into the pipeline.
4: When there are impurities in the fluid, filters should be installed to remove the fibers, particles and other impurities in the fluid.
5: When installing outdoors, there should be cover on the upper part of the controller, so as to avoid rainwater immersion or sunshine exposure affecting the normal use of the controller.
