Proline Promass H 300
Coriolis flowmeter

Chemically resistant single-tube flowmeter with a compact, easily accessible transmitter

• Measuring principle

  Coriolis

• Product headline

  Chemically resistant single-tube flowmeter with a compact, easily accessible transmitter.
  Highly accurate measurement of liquids and gases in applications requiring highest corrosion resistance.

• Sensor features

  Maximum safety for chemically aggressive fluids – corrosion‐resistant wetted parts. Fewer process measuring points – multivariable measurement (flow, density, temperature). Space‐saving installation – no in-/outlet run needs.
  Measuring tube made of Tantalum, Zirconium. Nominal diameter: DN 8 to 50 (³⁄₈ to 2"). Medium temperature up to +205 °C (+401 °F).

• Transmitter features

  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. Remote display available.
