Pemancar aliran DP multivariabel
Pemancar aliran dp multivariabel umumnya digunakan bersama dengan perangkat aliran tekanan diferensial seperti V-cone, Orifice-plate, Verabar, Nozzle, Venturi dll. Untuk secara langsung menampilkan aliran instan dan aliran total. Dibandingkan dengan pemancar aliran tekanan diferensial tradisional, pemancar aliran tekanan diferensial multi-Variabel sangat mengurangi biaya pemasangan dan pemeliharaan purna jual. Pemancar aliran tekanan diferensial multi-Variabel banyak digunakan dalam industri perminyakan, kimia, tenaga listrik, metalurgi, pembuatan kapal, Farmasi, tekstil, pembuatan kertas dan perlindungan lingkungan.
