Heinrichs Messtechnik GmbH Warning The device is of limited use for the metering of potentially hazardous liquids and gases. It is essential that the operator takes appropriate steps to ensure that in the event of a glass tube breakage, no personnel are harmed and no equipment is damaged.
Heinrichs Messtechnik GmbH 4. Operating Principle and System Configuration The measuring instrument composes of a float and a conical glass tube (M) A medium flows from the bottom to the top through the measuring ring, lifting the float in the process until the buoyancy force (A) and the weight of the float (G ) establish equilibrium.
Heinrichs Messtechnik GmbH 4.2 Float Types There are three types of floats on offer: A. Float without guide rod B. Guided float Float Reading Edge C. Viscosity stabile floats The following viscosity limits require a viscosity-stable float: Model Viscosity (mPas, cP) ≥...

Heinrichs Messtechnik GmbH 4.3.3 Adjusting and wiring of the limit switches When ordered, the limit switches are factory set at the ordered values. They can however be adjusted to suit the operators requirements. For re-adjusting an M4 nut (SW7) must be released until the clamping position can be adjusted. Now the limit switch can be slid into an it’s new position.

Heinrichs Messtechnik GmbH 6. Installation and Condition for use Operating Conditions / Installation 6.1.1 Installation conditions The device should be operated pursuant to the guidelines of VDE/VDI Code 3513, sh. 3. Measurable media are: 1) Liquids that exhibit sufficient flowability are devoid of solids, do not bond and do not tend to settle.
Heinrichs Messtechnik GmbH Before dismantling the device, check to ensure that all pipes are void of media, have been depressurised and have cooled down Should the inside of the device contain any foreign matter, it should be cleaned thoroughly with a brush and suitable cleaning agent. Deposits should be removed carefully. Before reassembly, any gaskets or O-rings shall be assessed for intactness.
