測(cè)量原理科氏力質(zhì)量流量計(jì)產(chǎn)品標(biāo)題Robust flowmeter with genuine loop-powered technology. Highest measurement performance for liquids and gases under varying, demanding process conditions.
傳感器特點(diǎn)Highest process safety – immune to fluctuating and harsh environments. Fewer process measuring points – multivariable measurement (flow, density, temperature). Space‐saving installation – no in/outlet run needs. Mass flow: measured error ±0.1 %. Medium temperature up to 205 °C (401 °F).
變送器特點(diǎn)Convenient device wiring – separate connection compartment. Safe operation – no need to open the device due to display with touch control, background lighting. Integrated verification – Heartbeat Technology. Loop‐powered technology. Robust dual- compartment housing.
