Ultrasonic Flow Meter GT 400
Ultrasonic Flow Meter GT 400
Seri GT400 adalah hasil pengembangan terbaru dari teknologi ultrasonic meter kelas atas. Sejak pertama kali RMG meluncurkan ultrasonic meter pada tahun 1999, prinsip pengukuran 6-jalur sudah digunakan untuk kebutuhan pengukuran transaksi (custody transfer). Pada generasi ke-4 saat ini, tersedia alat ukur yang sangat optimal untuk mengukur aliran gas dalam jumlah besar dengan tekanan tinggi di pipa maupun stasiun distribusi gas.
Dengan desain sensor yang tahan tekanan, alat ini memiliki tingkat kekuatan suara yang sangat tinggi sehingga tetap akurat dan tidak mudah terganggu meskipun dipasang dalam kondisi instalasi yang sulit.
Selain itu, semua meter gas ultrasonic GT400 dilengkapi dengan Virtual Meter Path Technology™ (VMPT). Teknologi ini memungkinkan pengecekan hasil pengukuran secara virtual tanpa perlu menambahkan komponen tambahan pada alat. Informasi lebih lanjut tentang VMPT bisa dilihat pada Tech Note 9 di halaman publikasi kami.
Spesifikasi Produk
Apparatus for measuring the volume of gas in legal metrology
- MID approved by the PTB
- High stability against pre-interference due to 6 direct measuring paths, arranged as X in 3 planes
- Tested according to TR G13 / OIML
- Air calibration with high pressure test according to TR G7
- High flow velocity (up to 40 m/s), therefore the use of smaller nominal sizes is possible
