The following mounting versions are recommended for the installation:
Lubricate all threaded joints prior to mounting. The screws for wall, tabletop or pipe
mounting are not supplied with the device and must be chosen to suit the individual
installation position.
Wall mounting

holder are designed to hook into the screws.
Mounting on a table
Screw the sensor holder onto the tabletop with four screws.
Pipe mounting
Secure the sensor holder to the pipe with two clamps.
WARNING

NOTICE
All Dosimass measuring instruments are calibrated in accordance with state-of-the-
art technology. Calibration takes place under reference conditions .
Zero adjustment is therefore not required for the Dosimass as a general rule.
‣
Experience shows that a zero adjustment is advisable only in special cases.
‣
When maximum measurement accuracy is required and flow rates are very low.
‣
Under extreme process or operating conditions (e.g. very high process temperatures or
very high-viscosity fluids).
Detailed information on reference operating conditions →  55
Prerequisites for zero adjustment
Note the following points before performing the adjustment:
• A zero adjustment can be performed only with fluids that contain no gas or solid
contents.
• Zero adjustment is performed with the measuring tubes completely filled and at zero
flow (v = 0 m/s (0 ft/s)). Shutoff valves, for example, may be provided for this purpose
or existing valves and sliders can be used.
• Normal operation → Valve 1 open
• Zero adjustment → Valve 1 closed
