Emerson Micro Motion 1600 Compact Coriolis Flow Transmitter

Emerson Micro Motion 1600 Compact Coriolis Flow Transmitter

The Emerson Micro Motion 1600 is a small Coriolis flow transmitter that can accurately monitor mass flow, density, and temperature in tough process settings. It has a lightweight, single-compartment design and versatile mounting choices, which make it perfect for confined locations and skid-based systems where footprint and wiring ease are very important.

The 1600 works with HART, Modbus/RS-485, and native Ethernet (EtherNet/IP, Modbus TCP, PROFINET), so it can be easily added to modern control systems. It also has optional Power over Ethernet (PoE) to save down on installation costs. An onboard data historian and advanced diagnostic software give users a lot of information about process stability, fluid quality, and device health. This helps them maximize uptime and measurement confidence.

MICRO MOTION 1600 Key Features:

1) The compact, single-compartment design makes it easier to install on skids, tight panels, and in distant locations.

2) HART 7, Modbus RTU/RS-485, EtherNet/IP, Modbus TCP, and PROFINET are all supported. You can also use PoE to send power and data over a single cable.

3) Data historian and diagnostic tools that work together to record events, check the quality of fluids, and check the stability of measurements over both short and long periods of time.

4) One customizable I/O channel that can output mA, frequency, or discrete signals, allowing for versatile control and monitoring.
