Deskripsi Produk
Instrumen Pengukuran Aliran yang Digunakan untuk Arc Furnace
Pemantauan aliran sangat penting untuk sistem air pendingin, sistem pengangkutan gas, dan manajemen energi. SAF dan EAF memerlukan pemantauan aliran air pendingin, aliran gas, aliran oksigen, dan aliran argon.
1. Pengukur Aliran
| Jenis | Prinsip Pengukuran | Media yang Berlaku | Rasio Penurunan | Ketepatan | Aplikasi |
|---|---|---|---|---|---|
| Pengukur Aliran Elektromagnetik | Hukum Faraday | Cairan konduktif (≥2,5μS/cm) | 10:1~100:1 | 0,5%~1,0% | Air pendingin, aliran cairan konduktif |
| Pengukur Aliran Pusaran | pusaran Karman | Gas, uap, cairan dengan viskositas rendah | 10:1~20:1 | 1,0%~1,5% | Uap, gas, aliran oksigen |
| Pengukur Aliran Massa Termal | Difusi termal | Gas | 50:1~100:1 | 1,5%~2,0% | Aliran massa gas, argon, nitrogen |
| Pengukur Aliran Tekanan Diferensial | Penurunan tekanan lubang | Gas, cair, uap | 3:1~4:1 | 1,5%~2,5% | Suhu tinggi, tekanan tinggi, misalnya aliran uap |
| Pengukur Aliran Massa Coriolis | gaya Coriolis | Cairan, gas, bubur | 100:1 | 0,1%~0,2% | Aliran massa presisi tinggi |
2. Sakelar Aliran
| Jenis | Rentang Pengaturan | Peringkat Kontak | Kelas Perlindungan | Aplikasi |
|---|---|---|---|---|
| Sakelar Aliran Baling-Baling | 0,5~10m/dtk | 5A/250VAC | IP65 | Alarm tanpa aliran air pendingin |
| Sakelar Aliran Termal | 0~5m/detik | 0,5A/24VDC | IP67 | Alarm aliran rendah gas/cair |
| Sakelar Aliran Piston | 0,5~15L/menit | 3A/250VAC | IP65 | Pemantauan aliran sistem pelumasan |
3. Referensi Pemilihan Instrumen Aliran
| Skenario Pengukuran Aliran | Instrumen yang Direkomendasikan | Alasan Pemilihan |
|---|---|---|
| Air pendingin (konduktif) | Pengukur aliran elektromagnetik | Tidak ada kehilangan tekanan, akurasi tinggi, tidak terpengaruh oleh suhu/tekanan |
| Air pendingin (non-konduktif/ultramurni) | Pengukur aliran ultrasonik | Non-kontak, tidak ada kehilangan tekanan |
| Aliran uap | Pengukur aliran pusaran / pengukur aliran DP | Ketahanan suhu tinggi, struktur sederhana |
| Gas/Oksigen/Argon | Pengukur aliran massa termal / Pengukur aliran pusaran | Aliran massa langsung, respon cepat |
| Pengelompokan presisi tinggi | Pengukur aliran massa Coriolis | Akurasi tertinggi, pengukuran kepadatan simultan |
| Alarm tidak ada aliran | Sakelar aliran | Sederhana, andal, berbiaya rendah |
