  • Page 7: Mechanical Installation

    Mechanical Installation 1.1 General principles The OPTIMASS mass flow meters provide high accuracy and excellent repeatability. Narrow band pass digital filtering, and the mathematically modelled internal primary head design with AST (Adaptive Sensor Technology) for the OPTIMASS sensor family provide exceptional immunity to external vibratory disturbances from nearby process equipment.

The use of reducers at the flanges is allowed. Extreme pipe size reductions should be avoided due to possibility of cavitation and degassing.

  • Page 11: Secondary Pressure Containment

    1.2.4 Secondary Pressure containment The OPTIMASS 7000 meters are supplied with secondary pressure containment as standard. Allowable maximum secondary containment pressures are 63 bar at 20°C or 914 psig at 70°F If the user suspects that the primary tube has failed, the unit must be depressurised and removed from service as soon as possible.

    Installation lengths For installation lengths, please see section 1.2.10 Please check with KROHNE if you are unsure of the installation length. Many meters are built to customer requirements / specifications especially where special hygienic process connectors have been adapted to the meter. As these are normally non-standard, the installation length will not be given in the technical data.

  • Page 15: Heating And Insulation

    1.2.7 Heating and insulation There are several methods to heat the meter. In most cases heating is unnecessary as the meter is designed as such that very little heat is lost or gained through the outer cylinder. Insulation Where insulation is required a variety of materials may be used to insulate the meter. Care must be taken not to insulate the meter above the halfway mark of the electronics support post as shown in the sketch.
  • Page 16 The maximum heating temperature for a Titanium meter is 150°C or 300°F. The maximum heating temperature for Hastelloy or SS meters is 100°C or 210°F. If these temperatures are exceeded, the meter will be damaged. KROHNE accepts no responsibility if this happens. Installation and Operating Instructions OPTIMASS...

  • Page 81 Flow direction Fct. 3.1.4 This function allows the user to select the direction of the flow measurement in relation to the arrows on the Front End housing. (see section 1.1 General Principles). ‘Forward’ is selected if the flow is in the same direction as the + arrow and ‘Backward’...
  • Page 82 Pressure Suppression Fct. 3.1.8 and 3.1.9 The Pressure Suppression feature eliminates any influences on the measurement result of sudden termination of flow, such as when a valve is shut. When this occurs the propagation of pressure waves along the pipe work and through the meter may produce an “Over-shoot” or “ringing” effect, where the flow rate will oscillate backwards and forwards until it settles to a stable zero flow condition, as is indicated in the diagram below.

  • Page 85 Velocity: Fct. 3.2.12 This function provides an additional measurement parameter. This is particularly useful when the velocity of hazardous materials is to be monitored where static build up is a danger. The mass flow meter will calculate the velocity based on the tube diameter and the mass flow rate. In this menu the units for velocity may be selected.
