Frequently Asked Questions (FAQ)

Q1. What is the Rosemount 8800D Vortex Flow Transmitter used for?
The 8800D is designed to measure the flow of steam, gas, and liquid in industrial processes. It is widely applied in power generation, chemical plants, oil & gas, and general utilities.

Q2. How does the 8800D measure flow?
It uses the vortex shedding principle, where vortices are formed as fluid passes a bluff body. The frequency of these vortices is directly proportional to the flow velocity, allowing accurate flow measurement.

Q3. What makes the 8800D different from other vortex flowmeters?
The 8800D features a gasket‑free, all‑cast body with no moving parts, eliminating potential leak points and reducing maintenance. It also offers dual and quad sensor configurations for safety‑critical applications.

Q4. What types of fluids can it measure?
It can measure saturated and superheated steam, compressed air, natural gas, industrial gases, cooling water, boiler feedwater, and a wide range of process liquids.

Q5. What is the accuracy of the 8800D?
Typical accuracy is ±0.65% of rate for liquids and ±1.0% of rate for gas and steam, with repeatability of ±0.2%.

Q6. What communication protocols are supported?
The transmitter supports 4–20 mA with HART, FOUNDATION Fieldbus, and Modbus protocols, ensuring compatibility with most control systems.

Q7. What installation options are available?
The 8800D is available in flanged, wafer, reducer, dual‑sensor, quad‑sensor, and high‑pressure designs, providing flexibility for different piping systems and process conditions.

Q8. Is the 8800D suitable for safety instrumented systems (SIS)?
Yes. Dual and quad sensor configurations are SIL‑certified, making them suitable for SIS applications where redundancy and reliability are critical.

Q9. What is the temperature and pressure range?
It can handle temperatures from –200 °C up to +400 °C and pressures up to ANSI Class 1500, depending on the configuration.

Q10. What are the maintenance requirements?
With no moving parts and a gasket‑free design, the 8800D requires minimal maintenance, reducing lifecycle costs and downtime.
