科里奥利质量流量
The genuine loop‐powered flowmeter for minimized cost of ownership. Highly accurate measurement of liquids and gases for a wide range of standard applications.
Cost-effective – multi-purpose device; an alternative to conventional volumetric flowmeters. Fewer process measuring points – multivariable measurement (flow, density, temperature). Spacesaving installation – no in/outlet run needs. Compact dual-tube sensor. Medium temperature up to +150 °C (+302°F).
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.
