Meternet I/0 is a unique distributed I/O system specifically designed to meet the demanding I/O requirements of flow metering systems.
Being of modular design Meternet I/0 is a cost effective solution, scaleable to meet the requirements of any size of installation.
The Meternet I/0 system provides a range of standard modules but more importantly is furnished with modules specifically designed for metering applications. No other system can collectively provide the complete range of required features in a single assembly e.g.;
• High accuracy analogue inputs (16 bit minimum)
• High accuracy frequency inputs (densitometer period measurement)
• Hart communications (digital transmitter interface)
• Dual pulse inputs with pulse integrity monitoring in accordance
with ISO6551
• Gated pulse counting with double chronometry, pulse interpolation
in accordance with API Manual of Petroleum Measurement
standards.
Central Processor
The Meternet I/0 P3-CPU provides communications via Modbus RTU (Serial) and Modbus TCP (Ethernet). OPC interface can also be provided via the Meternet I/0 OPC Server.
The P3 is a programmable device supporting all five IEC 61131 programme languages. This PLC functionality adds to the system flexibility and routines such as valve handling, meter proving sequencing and automatic sampling can be provided as embedded functions.
