Flow should be introduced to the meter gradually. Failure to do so may result in violent movement of the float causing damage to the instrument. Ball floats are always read at the horizontal diameter. READ HERE
The specified accuracy of this instrument only applies at the given operating conditions. Errors are introduced if there are variations in density or viscosity.
This is not a guarantee that tubes will not break within the operating limits due to circumstances beyond our control e.g. impact, thermal shock or incorrect installation.
Fluids containing small amounts of solid material can be tolerated, although this can increase wear and in some cases affect accuracy. It is recommended that a filter is installed if solids are present.
Glass tube flowmeters should only be operated with the protection shield in place. Limits of operation must always be observed. Failure to do so may result in damage and/or injury.

It is important that the wetted parts of the meter are compatible with the process fluid. The use of incompatible O-ring materials can cause the tube to break.
Instruction Manual
Operation
Glass metering tubes should not be used for either hot or strong alkalies, fluorine, hydrofluoric acid, steam or water above 93°C. These fluids can cause damage which is not always obvious on visual inspection.

Installation
The flowmeter must be installed vertically in the pipeline with the highest scale values at the top.
Maintenance
Warning. This may cause deterioration of optical and/or mechanical properties which could result in damage and/or injury. The only maintenance required is the occasional cleaning of the tube and float. The tube can be removed from the meter in situ. Proceed as follows. 1. Shut off flow to the meter. Drain or purge if possible. Be absolutely sure that all pressure has been relieved. 2. Remove the shield from the body by squeezing one side inward to disengage. 3. Remove the tube by pushing upwards against the spring then pull outwards (see diagram).
To reduce the risk of float oscillation it is recommended that the distances to the next throttling location upstream and downstream be kept to a minimum.

Note. If the instrument is to be used for Oxygen service a special grease must be used e.g. Voltalef 90.
D
7. Lightly grease all O-rings prior to replacement.
