2. Product Introduction
Severe chemical processing loops and high-enthalpy steam lines demand flow instrumentation capable of maintaining stable measurement profiles without moving parts that degrade under thermal shock. The 8810-HI-TX utilizes advanced vortex-shedding technology, incorporating an isolated sensor design that isolates the piezoelectric crystals from process vibration and fluid noise.
Plant operators rely on this high-temperature configuration to meter superheated steam and aggressive gases under extreme thermal envelopes. Its obstructionless bluff body design eliminates pressure drop across the pipe while delivering robust HART digital communication straight to the distributed control system.

4. Global Compliance & Industry Certifications
Auditors inspecting high-energy steam loops and hazardous process areas require verifiable documentation regarding explosion containment and material traceability.
- Expected Compliance Standards: CE Mark, ATEX / IECEx Explosion-Proof, CSA/FM Intrinsically Safe & Explosion-Proof, and PED (Pressure Equipment Directive) compliance.
- Safety Significance: The explosion-proof housing and dual-seal design ensure that volatile process gases or high-pressure steam cannot breach the electronics compartment, preventing ignition sources in classified hazardous process zones.
- Verify specific lot certifications and hazardous area classifications with Emerson / Rosemount or your regional compliance officer before line pressurization.
5. Long-Term Storage & Asset Preservation Guide
Heavy industrial flowmeters stored in warehouse inventories require specific protection protocols to prevent sensor degradation and terminal oxidation.
Keep the meter stored horizontally on a secured pallet inside a climate-controlled room where relative humidity stays below 60%. Leave the protective plastic flange covers securely bolted to the process connections to prevent foreign debris, dust, or moisture from contaminating the internal bluff body and sensor vortex shedder. Inspect the terminal compartment yearly to ensure no condensation has formed inside the electrical conduit entries.
6. Physical Installation Prerequisites
Accurate vortex measurement relies heavily on fully developed velocity profiles free from upstream flow disturbances. Ensure a minimum of 15 pipe diameters of straight upstream run and 5 pipe diameters of downstream straight run free of valves or elbows. Install the meter with the flow arrow matching the exact direction of the process fluid, and ensure the pipeline is completely anchored to eliminate external pipe stress.
7. Buyer’s FAQ
- What is the proper Harmonized System (HS) tariff code for international customs clearance of this flowmeter?
- Industrial flow measurement instruments generally fall under HS Code 9026.10 (Instruments and apparatus for measuring or checking the flow or level of liquids). Confirm exact bindings with your customs broker.
- Does this unit arrive pre-configured with line sizing parameters?
- Rosemount meters are typically factory-configured to customer specifications; however, range, damping, and units must be verified using a HART communicator during initial staging.
- What logistics considerations apply regarding the Country of Origin (COO)?
- Manufacturing origins for Rosemount vortex meters typically trace to the United States or Singapore; check the exterior crating label for exact traceability records.
- What packaging precautions are mandatory for freight transport?
- Ship the flowmeter bolted to a custom wooden pallet or inside a heavy-duty crating box with high-density foam bracing to protect the electronics neck and flange faces from drop shocks during transit.
