DWYER Series VA Variable Area Glass Flowmeters

Series VA Variable Area Glass Flowmeters

Pengukur Aliran Kaca Area Variabel SERIES VA dirancang dengan skala mm universal yang mudah dibaca dan dilengkapi dengan grafik korelasi yang berisi data kalibrasi untuk udara dan air.
Pengukur aliran kaca cocok untuk mengukur gas pembawa, pengukuran cairan dan gas di pabrik percontohan, laboratorium, aliran proses, dan indikasi level.
Unit dilengkapi dengan katup jarum 6 putaran standar untuk kontrol laju aliran. Katup pengukur presisi tinggi dengan batang tidak naik (dijual terpisah) tersedia untuk kontrol dan resolusi sensitivitas tinggi – sangat cocok untuk laju aliran yang sangat rendah.
Flowmeter dikirim dalam keadaan lengkap dan siap untuk dipasang di panel. Gunakan alas tripod akrilik opsional untuk mengubahnya menjadi dudukan bangku berdiri sendiri.

Permanently fused ceramic scale with vertical locator line reduces parallax and eye fatigue saving time
Long operating life with thick polycarbonate front shield that protects tube from breakage and serves as a magnifying lens to enhance reading resolution
Standard 6-turn needle valve for flow rate control eliminating the need for a separate valve reducing cost
No additional installation required with optional acrylic tripod base which allows for self-standing bench mounting
High precision metering valves with non-rising stems are available for high sensitivity control and resolution for very low flow rate
