> ⚠️ Important distinction: 8800DW = Wafer type; 8800DF = Flanged type. Their face-to-face lengths differ completely and cannot be interchanged.
- Straight Pipe Requirements (Mandatory for measuring accuracy, D = DN25)
- Upstream, no flow disturbances (straight pipe without valves or elbows): ≥10D (≥250 mm)
- Downstream (universal requirement): ≥5D (≥125 mm)
- Single in-plane 90° elbow upstream: ≥20D
- Two out-of-plane 90° elbows upstream: ≥30D
- Control valves must be installed downstream of the flowmeter. If valves are fitted upstream, upstream straight pipe length ≥50D.
- Installation Orientation Guidelines (ไอน้ำ / ของเหลว / Gas service)
- Saturated steam measurement (most common working condition)
Preferred arrangement: Horizontal pipeline, transmitter head mounted horizontally sideways (prevents condensate from flowing into sensor support)
Do NOT mount transmitter head vertically downward
- Liquid service
Horizontal installation recommended. For vertical piping, fluid must flow upward only. Downward flow is prohibited (risk of gas entrapment and incomplete pipe filling)
Avoid installation at pipeline high points (gas accumulation)
- Gas service
Horizontal or upward vertical installation preferred; avoid low points where liquid may collect
- ข้อห้ามในการติดตั้งที่เข้มงวด
- Thermal insulation shall not cover the lower section of transmitter support to avoid overheating electronics (maximum ambient temperature: 85℃).
- Flange gaskets must not intrude inward into the pipeline bore during assembly.
- Upstream and downstream piping must be concentric; misalignment shall be less than 0.5 มม.
- Keep away from strong vibration sources such as reciprocating pumps and compressors. If vibration is unavoidable, install pipe supports at 2D upstream and downstream.
- The 8800D body does not come with an integrated flow conditioner. Install a pipeline flow conditioner if sufficient straight pipe cannot be provided.
