測量原理 | Coriolis |
Product headline | The genuine loop‐powered flowmeter for minimized cost of ownership. Highly accurate measurement of liquids and gases for a wide range of standard applications. |
Sensor features | Cost‐effective – multi‐purpose device; an alternative to conventional volumetric flowmeters. Fewer process measuring points – m*riable measurement (flow, density, temp). Spacesaving installation – no in/outlet run needs. Compact dual‐tube system. Medium temperature up to +140 °C (+284 °F). |
Transmitter features | Convenient device wiring – separate connection compartment. Safe operation – no need to open the device due to display with touch control, background lighting. Automatic recovery of data for servicing. Loop‐powered technology. Robust two‐chamber housing. |
