Closing of Valve before Zero-Point Calibration
It is necessary to do zero-point calibration after the installation is completed. Close
the downstream stop valve before zero-point calibration, and then close the upstream
stop valve.

Installation Direction
3.2.1
Horizontal and Vertical Installation
The Tek-Cor 1100A should be installed in the orientation that can ensure the
measuring tube is filled with the medium being measured.
Standard Installation
Picture-1 Picture-2 Picture-3
For Liquid For Gas For Slurry
For horizontal installation, the measuring tube should be installed downside of the
pipeline when the process medium is liquid or slurry (Picture 1); upside of the pipeline
when the process medium is gas (Picture 2). For vertical installation, the measuring
tube should be installed besides the pipeline when the process medium is liquid or
slurry or gas (Picture 3).
3.2.2
Difficult Installation Location for Liquid and Gas Measurement
The flow meter must not be mounted at the highest point of the tubing (A) if gas
bubbles are expected, or at the lowest point (B) if solid particles are expected. Also,
the meters must not be mounted in a drop-line near the open end (C), to avoid the
flow meter becoming empty.
