Endress+Hauser  e+h夹持型涡街流量计7D2B特征和规格

测量原理涡街
主要特点The flowmeter with a cost‐effective wafer design, available as compact or remote version. Integrated temperature measurement for mass/energy flow of saturated steam. For all basic applications and for 1‐to‐1 replacement of orifice plates.
特点Easy alignment of the sensor – included centering rings. High availability – proven robustness, resistance to vibrations, temperature shocks & water hammer. No maintenance – lifetime calibration. Face‐to‐face length of 65 mm (2.56 in). No flanges.
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.
