Signet Flow Sensor 525 Metalex
The Signet 525 Metalex ™ Paddlewheel Flow Sensor menggabungkan konstruksi baja stainless dengan teknologi paddlewheel penyisipan (signet 515). Sehinnga tahan terhadap tekanan dan suhu ekstrem. Poros Tungsten Carbide dengan bantalan PTFE yang diperkuat serat karbon memberikan ketahanan aus yang sangat baik untuk layanan yang lebih lama.Program pemasangan komprehensif memungkinkan pemasangan saluran baja dengan kunci mini untuk diameter kecil, dan tap mini untuk pipa hingga DN300 (12 in.). Output sinyal yang diproduksi sendiri menggunakan monitor aliran yang dioperasikan dengan baterai Signet 8150.
