Tips Mengaplikasi Flowmeter LC

Summary

Positive displacement flow meter Liquid Control memiliki akurasi yang sangat baik yakni dari 0.2-0.3% error dan 0.05% pengulangan akurasi. Maintenance yang rendah sehingga,tidak ada kontak antara logam ke logam. Pressure loss juga sudah sangat rendah. Tergantinya jangka akurasi juga minimal […]

Positive displacement flow meter Liquid Control memiliki akurasi yang sangat baik yakni dari 0.2-0.3% error dan 0.05% pengulangan akurasi.

Maintenance yang rendah sehingga,tidak ada kontak antara logam ke logam. Pressure loss juga sudah sangat rendah. Tergantinya jangka akurasi juga minimal dari waktu ke waktu,jadi tidak butuh untuk kaliberasi ulang dalam jangka waktu pendek, dan memiliki masa pakai lebih lama.  Meter sesuai dengan persyaratan akurasi NIST atau badan meterologi di Amerika.

Tidak diperlukan daya listrik untuk beroperasi, flow meter Liquid Controls bisa beroperasi secara mandiri (untuk unit yang dilengkapi dengan register mekanik, printer, atau preset); tidak ada persyaratan perpipaan khusus. Flow meter Liquid Control juga memiliki kisaran jangka suhu yang luas — cairan bisa mulai diukur dari suhu -40 C sampai 70 C.

Flow meter juga bisa mengukur dalam jangka kekentalan yang luas— LC meter dapat secara akurat mengukur cairan dengan kekentalan yang kurang dari 30 SSU (kurang dari 1 cps) hingga sekental 1.500.000 SSU (325.000 cps).  Adaptasi maksimum — Flow meter Liquid Control sudah didesain dengan pilihan stok atau flange khusus memberikan fleksibilitas pemasanga yang efisienuntuk memenuhi persyaratan instalasi segala macam pipa sesuai kebutuhan anda.

Flow meter juga bisa menahan tekanan maksimum sebesar 150psi / 10,5 BAR atau (350psi/24 Bar (hanya ekslusif untuk seri MA-4, MA-5, MA-7, MA-15)

Spesifikasi Liquid Control Flow Meter

Flowmeter LC sudah memenuhi NTEP (Buku Pegangan NIST 44) dan banyak persyaratan ketepatan Pengukuran dan Berat Internasional, serta spesifikasi Militer A.S.
