Hygienic installation in three steps: positioning, connection, commissioning
Step 1: System Positioning
- Orientation: Install horizontally or vertically (upward flow preferred). Avoid air entrapment at high points. Position for complete drainage during CIP.
- Straight Pipe: Minimum 3D upstream, 2D downstream. Compact requirements enable tight skid integration.
- Access: Ensure tri-clamp ferrule accessible for removal without disturbing adjacent piping.
Step 2: Tri-Clamp Connection
- Slide tri-clamp ferrules onto pipe ends
- Position gasket between ferrule faces (ensure proper centering)
- Install tri-clamp band and tighten evenly
Gasket Selection: Match gasket material to process fluid and temperature. EPDM standard; Viton for oils/fats; PTFE for high-purity.
Alignment: Verify flow direction arrow matches process flow. Electrode orientation not critical (self-compensating).
Step 3: Electrical & Commissioning
- Power: Connect AC or DC power per voltage rating. Converter may be integrated or remotely mounted (split configuration).
- Grounding: Ground flowmeter to facility ground. Non-conductive gaskets may require grounding rings.
- Zero Calibration: Fill pipe with static process fluid. Execute zero adjustment. Verify <0.1% of full scale.
- CIP Verification: Run CIP cycle. Verify cleanliness. Confirm zero stability post-cleaning.
Critical Requirements
- Drainage: Install with slight slope for complete drainage. Eliminate low points where product can pool.
- Air Elimination: Avoid high points. Provide air bleed if required by process piping configuration.
- CIP Flow: Ensure CIP flow rate sufficient to clean electrode surfaces (minimum 1.5 m/s velocity recommended).
