測(cè)量原理渦街主要特點(diǎn)The flowmeter with the same accuracy despite line size reduction, available as compact or remote version. Integrated temperature measurement for mass/energy flow of saturated steam. Dedicated for applications with very low or reduced flow.
特點(diǎn)Cost and time saving – no pipework modifications needed for line size reduction. High availability – proven robustness, resistance to vibrations, temperature shocks & water hammer. No maintenance – lifetime calibration. Integrated diameter reduction by 1 or 2 line sizes. Nominal diameter (mating pipe) up to DN 250 (10").
Transmitter featuresConvenient 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. Display module with data transfer function. Robust two‐chamber housing.
