8800 Vortex Flow Meter: Rosemount Saturated Steam Processing System Manuals
Quick Answer: The Rosemount 8800 vortex flow meter works on saturated steam lines from DN15 to DN300 when the steam pressure and temperature stay stable. The Rosemount saturated steam processing system manuals for the 8800 cover wiring, K-factor settings, and HART menus. But they do not cover every steam quality issue in the field. Silver Instruments supplies vortex meters with 4-20 mA HART, PT100 input, and flange or wafer bodies for saturated steam processing systems. Send us your pressure, temperature, pipe size, and flow range for a quote.
What the 8800 Manuals Cover for Saturated Steam
The Rosemount 8800 manual gives you the density compensation formula for saturated steam. A DN80 line at 7 bar saturated steam has a density close to 3.6 kg/m3. Mass flow equals volumetric flow times density. The meter needs a pressure input or a fixed process pressure to calculate mass flow. Most engineers skip this part.
In practice, steam pressure moves more than the manual suggests. A boiler in a Philippine palm oil mill may swing from 6 bar to 8 bar during load changes. If the meter uses a fixed pressure value, the mass flow reading shifts by more than 4 percent. We have seen this on customer sites many times.
Saturated Steam Pipe Sizes and Common Flow Ranges
Saturated steam lines in food plants, textile mills, and chemical sites often run from DN25 to DN150. A small DN25 line at 4 bar handles 80 to 400 kg/h. A DN100 line at 8 bar can pass 1200 to 8000 kg/h. Vortex meters suit these ranges because they have no moving parts and tolerate steam temperature up to 250 °C or higher with high temperature versions.
Silver Instruments supplies vortex flow meters for DN15 up to DN300. For saturated steam we recommend the VF series with integrated PT100 temperature compensation and 4-20 mA HART output. The same body works in Papua New Guinea, New Zealand, Vietnam, Mexico, Saudi Arabia, and Kenya without changes. Local flange standards vary, so state whether you need ANSI 150, ANSI 300, PN16, or PN40.
Installation Notes the Manuals Do Not Mention
Here is the thing. Steam lines vibrate. Vortex meters count vortices and vibration can add false counts. A dairy in New Zealand had unstable readings on a DN65 steam line at 5 bar. The pipe support was too far from the meter. After they moved the support and added a straight run of 15 pipe diameters before the meter, the signal stabilized.
Condensate also causes errors. Install the meter on a horizontal line with flow upward if possible. Put drain pockets before the meter. Wet steam or two phase flow damages the bluff body signal and gives sp
Silver Instruments Vortex Meter Options for Steam Service
Our VF series vortex flow meter covers saturated steam, superheated steam, air, nitrogen, and water. The sensor body comes in 304 stainless steel or 316L. For steam above 180 °C we use a sensor with an extended neck or remote electronics. Output signals include 4-20 mA HART, pulse, and RS485 Modbus. Optional ATEX Zone 1 approval is available for classified areas. We also supply pressure transmitters and paperless recorders in one package if you need a complete steam monitoring loop.
The 8800 meter and our VF series share similar installation dimensions for many pipe sizes. Before you replace an old 8800, send the flange size, flange rating, K-factor tag, and HART device revision. We will match the mechanical face and configure the new meter to the same range.
What to Send Us for a Saturated Steam Quote
Do not send a general request. We need specific data. State the steam pressure in bar, the temperature in °C, the pipe size in DN, the flow range in kg/h, and the flange standard. Also tell us if you need HART or Modbus and if the area has hazardous classification. We will reply with a model number, accuracy curve, wiring diagram, and price within one business day.

FAQ
Can the 8800 vortex flow meter measure saturated steam mass flow?
Yes. The meter calculates mass flow when the pressure or temperature compensation is active. You must configure the correct steam properties in the transmitter.
What pipe sizes suit saturated steam vortex measurement?
DN15 to DN300 covers most small and medium steam systems. For DN350 and larger, contact Silver Instruments for a specific proposal.
Do I need an external PT100 sensor for saturated steam?
Not always. Silver Instruments VF series can include a built-in PT100 or accept a 4-20 mA temperature signal. A pressure transmitter input is also available for density compensation.
Can Silver Instruments replace a Rosemount 8800 meter?
Yes in most cases. Confirm the flange face, K-factor, and HART device revision. We usually match the process connection and signal wiring.
What is the delivery time for a vortex flow meter for steam?
Standard DN15 to DN200 units ship in 7 to 15 days. Large sizes and special flanges may take 20 to 30 days.
