How to choose between electromagnetic, vortex, thermal mass, and differential-pressure flowmeters — and which of our models fits your medium, range, and accuracy.如何在电磁式、涡街、热式质量与差压流量计之间做选择——以及我们的哪款型号契合您的介质、量程与精度。Cara memilih antara flowmeter elektromagnetik, vorteks, massa termal, dan diferensial-tekanan — serta model mana yang cocok untuk medium, rentang, dan akurasi Anda.Cách chọn giữa lưu lượng kế điện từ, xoáy, khối lượng nhiệt và chênh áp — cũng như model nào phù hợp với môi chất, dải đo và độ chính xác của bạn.วิธีเลือกระหว่างโฟลว์มิเตอร์แบบ electro-magnetic วนกลับความร้อนและ difference-pressure — รวมถึงโมเดลใดที่เหมาะกับสื่อ ช่วงวัด และความแม่นยำของคุณCara memilih antara flowmeter elektromagnetik, vorteks, jisim terma dan perbezaan-tekanan — serta model mana yang sesuai untuk medium, julat dan ketepatan anda.Paano pumili sa pagitan ng electromagnetic, vortex, thermal mass, at differential-pressure flowmeter — at alin sa aming mga model ang babagay sa iyong medium, range, at accuracy.
The first question is always: what are you measuring, and what do you need from the measurement?第一个问题永远是：您在测量什么，又需要从测量中获得什么？Pertanyaan pertama selalu: apa yang Anda ukur, dan apa yang Anda butuhkan dari pengukuran?Câu hỏi đầu tiên luôn là: bạn đang đo gì, và bạn cần gì từ phép đo?คำถามแรกเสมอคือ: คุณกำลังวัดอะไร และคุณต้องการอะไรจากการวัดSoalan pertama sentiasa: apa yang anda ukur, dan apa yang anda perlukan daripada pengukuran?Ang unang tanong ay laging: ano ang sinusukat mo, at ano ang kailangan mo sa pagsukat?

|---|---|---|---|
| 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 |
Once you know the technology, the remaining decisions are pipe size, accuracy class, and process conditions.确定技术路线后，剩下的决策就是管径、精度等级与工艺条件。Setelah mengetahui teknologinya, keputusan berikutnya adalah ukuran pipa, kelas akurasi, dan kondisi proses.Khi đã biết công nghệ, các quyết định còn lại là kích thước ống, cấp chính xác và điều kiện quy trình.เมื่อทราบเทคโนโลยีแล้ว การตัดสินใจที่เหลือคือขนาดท่อ ระดับความแม่นยำ และเงื่อนไขกระบวนการSetelah mengetahui teknologi, keputusan seterusnya ialah saiz paip, kelas ketepatan dan keadaan proses.Kapag alam mo na ang technology, ang natitirang desisyon ay pipe size, accuracy class, at process conditions.
