主要特點 |
The genuine loop‐powered flowmeter for minimized cost of ownership. Highly accurate measurement of liquids and gases for a wide range of standard applications. |
|
特點 |
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 system. Medium temperature up to +150 °C (+302 °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. Integrated verification – Heartbeat Technology. Loop‐powered technology. Robust twochamber housing. |
