Overview

The compact orifice plate with OPTIBAR DP transmitter is an economic DP flowmeter for a broad range of applications – from demi-water to chemicals to steam. The integral orifice plate is a one-piece design per ISO 5167-2 or ASME MFC-3M, consisting of a compact orifice plate, a sandwich meter body, impulse lines and a connection flange. KROHNE offers the complete DP flow solution with integral orifice plate, manifold and DP transmitter. It comes pre-assembled, preconfigured and pressure tested – ready for immediate commissioning. There is absolutely no need for routing of impulse lines, valves and supports. In this way, material costs and installation efforts are significantly reduced.

  • Reduced installation costs: no installation of further components such as valves, DP transmitter, impulse lines, supports
  • No external impulse lines: reduced risk of leakage
  • Standardised flow element according to ISO 5167-2
  • Low TCO due to reduced engineering, commissioning and installation costs
  • Reduced need for recalibration in the field through advanced 3-D linearised OPTIBAR DP transmitters
  • Complete flowmeter solution with compact orifice plate, manifold, DP transmitter, sizing and documentation from a single source
  • Standard material: 316/316L, other materials on request
  • Redundant versions, pressure and temperature compensated versions available
  • Redundancy available (1oo2, 2oo3)
  • HART®7, Foundation fieldbus and Profibus-PA communication options
  • SIL 2/3 certified versions
  • Ex ia, Ex d approvals
