Applications
The main application for the type-approved SONO 3500 CT flowmeters is measurement of
water flow in district heating plants, local networks, boiler stations, substations, chiller plants,
irrigations plants, and other general water applications.
Integration
The flowmeter pulse output is often used as input for an energy meter or as input for digital
systems for remote reading. The transmitter has two pulse outputs, with functions that can
be individually selected, and integrated IRDA (optical eye) communication interface (Modbus
RTU).
The settings of the transmitter, for example flow and pulse output rate, are defined when
ordering the complete flowmeter. If the flowmeter forms part of an energy meter system for
custody transfer, no further approvals are needed, except possible local approvals.
Transmitter communication solutions
The transmitter supports Modbus RTU communication via the optical IrDA interface at the
display, enabling the change of different transmitter settings using the SIMATIC PDM
software tool.
The transmitter is configured in a combination of hardware (HW) and firmware (FW). For the
communication and parametrization via SIMATIC PDM a firmware-specific device
description (EDD) is needed.
