SMART-PULP Calibration
• The transmitter's memory circuits contain calibration curves adapted for all known unmixed pulps and all sensor models.
• Easy calibration. You just select the sensor type, pulp grade and mounting position, and check the consistency level at a single point.
• Compensation for ash is possible. • For unknown pulp types or pulp mixes you can create their own
curves or adapt a standard calibration curve through two points

You can make the selection as follows:
You can pre-select up to eight (8) calibration curves included in Smart-Pulp's memory circuits:
• using SMART-PULP operator terminal or
• through the HART terminal or • through three binary inputs

ASPE- Mounting pipe element
eliminates process disturbances
• Feature / User advantage: The ASPE mounting pipe element comprises the following components:
- 1. Flow straightener plates Ensures laminar flow upstream of transmitter. Transmitter can be installed relatively close to pump (small measurement lag).
- 2. Impact guards on both sides of transmitter Lumps that form especially during shutdown will be broken to prevent transmitter damage.
- 3. Mounting coupling pre-welded on element Coupling´s correct orientation is ensured.
FACILITATES PIPEWORK DESIGN, INSTALLATION AND MAINTENANCE.
ENSURES GOOD RESULTS.
