  特征和规格

  测量原理	科氏力质量流量计
  产品标题	The single‐ ube flowmeter for smallest flow quantities with an ultra‐compact transmitter. Measuring accurately smallest quantities of liquids and gases for continuous process control.
  传感器特点	Highest process safety – self‐drainable measuring tube design. Fewer process measuring points – multivariable measurement (flow, density, temperature). Space‐saving installation – no in/outlet run needs. Nominal diameter: DN 1 to 4 (¹⁄ to ¹⁄"). Process pressure up to 400 bar (5800 psi).
  变送器特点	Full access to process and diagnostic information – numerous, freely combinable I/Os and fieldbuses. Reduced complexity and variety – freely configurable I/O functionality. Integrated verification – Heartbeat Technology. Compact dual-compartment housing with up to 3 I/Os. Backlit display with touch control and WLAN access.
