2. TECO Stockrite™ Family of Consistency Transmitters
TMC6000 Transmitter
The TMC-6000 Microprocessor Consistency
Transmitter is designed as the backbone for the
TECO StockriteTM family of consistency
instrumentation; to be used as the common
electronics support platform for all of TECO’s family
of consistency probes.
The TMC-6000 is a remote mounted unit, making it
an excellent choice for high vibration, high
temperature, or inaccessible applications.
Its microprocessor based electronics allow the user
to have a set of predefined calibrations for easy set-
up and calibration. Users can also retain up to (10)
ten different calibration parameters to accommodate
different grades or stock furnish mixes.
The TMC-6000 also allows for “active velocity
compensation” which significantly increases overall
application range and maintains accuracy as your
production rate changes, unlike standard
mechanical devices.

4. DrainacTM IIIB Online Freeness Transmitter
Description
The DrainacTM operates on the basic principle of how easily water will drain through a pad of fiber.
Approximately every 30 seconds, the DrainacTM measures the rate of filtrate flow though a fiber pad.
The DrainacTM consists of a totally enclosed vertical riser which has no moving parts. The compact
detector is mounted directly in a pressurized stock line, or open vessel, avoiding any sampling lags or
transport delay time. For pressurized applications, stock rises into the detector tube under controlled
differential pressure. Fibers are retained on a perforated plate and filtrate passes through the pad
which is formed. The time required to draw a known volume of filtrate through the pad is used to
calculate freeness. For non-pressurized applications, the DrainacTM employs negative pressure to draw
the stock sample into the detector tube for drainage rate determination.
Once the freeness has been determined, air pressure is increased to return the filtrate and fiber to the
stock line in preparation for the next cycle. At the same time, flush water is introduced into the chamber
to clean the screen and the interior of the chamber. Cycle time ranges from 30-60 seconds.
