Rosemount Vortex Flowmeter 8800D 8600 Vortex Flow Meter Steam Flow Meter

Rosemount vortex Flowmeter 8800D 8600 Vortex Flow Meter Steam Flow Meter

The Rosemount 8600 Series from Emerson is a robust vortex flow meter engineered for accurate and repeatable measurement of liquids, gases, and steam. It’s widely used in utility systems, energy management, and process control environments where reliability, minimal maintenance, and digital communication are essential.

How It Works (Operating Principle)

The 8600 uses the vortex shedding principle:
As a fluid flow past a bluff body (shedder bar) in the meter, vortices are shed alternately from each side. The frequency of these vortices is directly proportional to the flow rate. A piezoelectric sensor detects the vortices and converts the signal into a digital flow reading.

Key Features & Technical Advantages

Multivariable Measurement (MTA Version)

• Integrates temperature and mass flow measurement without external RTDs.
• Ideal for saturated or superheated steam.
• Helps calculate mass flow or energy (BTU) directly in the transmitter.

Smart Electronics

• Supports HART® 5/7, Foundation Fieldbus, and pulse outputs.
• Optional diagnostics and simulation mode for commissioning and troubleshooting.
• Configurable via handheld communicator or PC software.

Mechanical Design

• No moving parts, minimizing wear and maintenance.
• Compact body allows for easy inline or remote mounting.
• Wetted materials: CF8M/CF3M stainless steel, corrosion-resistant.
• Available with flanged, wafer, or reducer-style configurations.

Performance Specifications

Installation Guidelines

• Straight Run Requirements: Typically 10 pipe diameters (upstream) and 5 diameters (downstream). Reducer versions reduce straight run needs.
• Orientation: Horizontal, vertical, or inclined installation.
• Remote Mount Option: Transmitter electronics can be located up to 23 meters (75 ft) away from the sensor body.

Application Examples

Steam Measurement

• Saturated and superheated steam in boiler systems
• Ideal for energy balancing and utility billing

Compressed Air & Gases

• Factory compressed air systems
• Natural gas, nitrogen, or CO₂ process lines

Liquids

• Cooling water or condensate return in industrial HVAC
• Chemical feed water or process liquid monitoring
