KEPmeter ES-749 Utility Metering Flow Computer

KEPmeter ES-749 Utility Metering Flow Computer untuk berbagai jenis flowmeter dalam aplikasi cairan, gas, uap, dan panas. Beberapa persamaan aliran tersedia dalam satu instrumen dengan banyak fitur lanjutan. Tampilan alfanumerik menawarkan parameter terukur dalam format yang mudah dipahami. Akses manual ke pengukuran dan pengguliran tampilan didukung keserbagunaan Flow Computer memungkinkan ukuran keserbagunaan yang luas dalam paket instrumen. Berbagai masukan dan keluaran perangkat keras dapat ditetapkan secara "lunak" untuk memenuhi berbagai kebutuhan aplikasi umum. Pengguna “memilih lembut” penggunaan setiap input/output saat mengonfigurasi instrumen.

Fitur KEPmeter ES-749 Utility Metering Flow Computer

Aplikasi KEPmeter ES-749 Utility Metering Flow Computer, meliputi: Massa Uap, Panas Uap, Gas Alam, Bahan Bakar 0il, Udara Terkompresi, Hanya Air Dingin, dan Hanya Air Panas termasuk Cutout DeltaT Rendah. Keluaran analog terisolasi dapat dipilih untuk mengikuti aliran volume, aliran volume terkoreksi, aliran massa, aliran panas, suhu, tekanan, atau densitas melalui pemilihan menu.

Sebagian besar fitur perangkat keras dapat dialihkan dengan metode ini. Pengguna dapat menetapkan Port Serial RS-232 standar untuk pencatatan data eksternal, pencetakan transaksi, atau untuk koneksi ke modem untuk pembacaan meter jarak jauh. Mode Layanan atau Tes disediakan untuk membantu pengguna selama pemeriksaan sistem start-up dengan memantau input dan menjalankan output. Pengaturan sistem juga dapat dicetak.
