Paano pumili sa pagitan ng electromagnetic, vortex, thermal mass, at differential-pressure flowmeter — kasama ang wastewater flow meter at coriolis flow meter — at alin sa aming mga model ang babagay sa iyong medium, range, at accuracy.
Ang unang tanong ay laging: ano ang sinusukat mo, at ano ang kailangan mo sa pagsukat?
| Technology | Best for | Key limits | Models |
|---|---|---|---|
| Electromagnetic | Conductive liquids (≥1–5 uS/cm), water & wastewater, slurries, clean water | Cannot measure gases, steam, or non-conductive liquids | SE11E · SE10A · SE11H · SE13E · SEB600S |
| Vortex | Steam, gas, and liquid — one meter for all three; low maintenance | Accuracy affected by vibration; needs reasonable flow velocity | SV21 · SV23 · SVH |
| Thermal mass | Direct gas mass flow — no separate temperature/pressure compensation | Gas applications only; not for liquids | ST51 · ST54 |
| Differential pressure | Budget large-pipe measurement, high-temp/high-pressure, dirty or viscous media | Lower accuracy, higher permanent pressure loss (except SD41/SD42) | SD40 · SD41 · SD42 · SD43 · SD45 |
| Variable area (rotameter) | Simple, cost-effective local indication of liquid/gas/steam flow | Manual reading; needs transparent line or indicator | SR41 |
Kapag alam mo na ang technology, ang natitirang desisyon ay pipe size, accuracy class, at process conditions.
| Model | Technology | Pipe range | Accuracy | Fluid temp |
|---|---|---|---|---|
| SE11E | Electromagnetic | DN3–2000 | ±0.2 / ±0.3 / ±0.5% | -25~200°C |
| SE10A | Electromagnetic (24V DC) | DN10–300 | ±0.5% | -25~180°C |
| SE11H | Electromagnetic (slurry) | DN3–2000 | ±0.2 / ±0.3 / ±0.5% | -25~200°C |
| SE13E | Electromagnetic (sanitary) | clamp connection | ±0.5% | food/pharma grade |
| SEB600S | Electromagnetic (battery) | DN15–300 | ±0.5% | no power line needed |
| SV21 | Vortex | DN15–300 | liq ±0.75% · gas ±1.0% | -40~350°C |
| SV23 | Vortex (sanitary) | clamp connection | liq ±1.0% · gas ±1.5% | food/pharma/steam |
| SVH | Vortex (digital) | DN15–300 | liq ±0.75% · gas ±1.0% | -40~260°C |
| ST51 | Thermal mass | flange/thread/insert | ±1.0% (gas mass) | up to 100:1 turndown |
| SD41 | Balanced (DP) | DN25–1000 | liq ±0.5% · gas ±1.0% | 0.5D–2D straight run |
| SR41 | Variable area | DN15–150 | 1.5 / 2.5 class | -40~250°C |

Ang vortex flowmeter ay angkop para sa steam, gas, at malinis na liquid o vapor, at kayang tumagal sa mas mataas na temperatura at pressure. Piliin ang magnetic para sa conductive fluids, vortex para sa gas/steam o kung kailangan ang mas malawak na fluid range.
Oo. Maglaan ng humigit-kumulang 5xDN na straight pipe sa upstream at 2xDN sa downstream upang patatagin ang flow profile; gumamit ng flow conditioner kung masikip ang space. Kailangan din ng straight runs ang vortex meters (humigit-kumulang 10-20xDN sa upstream) upang tumpak na masukat ang vortex frequency.
Oo. Dahil walang obstructing parts, mahusay na hinahawakan ng magnetic flowmeter ang maruming tubig, sludge, at slurry. Ang tanging hinihingi ay conductive ang liquid (conductivity na higit sa humigit-kumulang 5 uS/cm) at compatible ang liner sa liquid.
