FOR ALL INDUSTRIAL USES
• Graduated measuring ranges according to DIN, from 3 to 50.000 l/h.
• DN10 to DN65 graduated tubes.
• Tube lenghts = type description 165 to 350 mm.
• Materials for (almost) all media: uPVC, PA, PSU, PVDF.
• Process automation using limit signal transmitters and measured
value remote transmission (optional).
HIGH ACCURACY AND OPERATIONAL RELIABILITY
• Indicator accuracy according to VDI/VDE 3513.
• Materials with reduced moisture absorption increase the
measured value stability.
• Pressure level PN10, materials with high impact resistance
and increased creep strength
• Hermetically sealed, connected with o-rings.
• Require little maintenance, install radially.
The medium , water, air, liquid, or gaseous chemicals flow
vertically from the bottom to the top. The flow forced cause
the float to lift with-out friction and its top graduation edge
(largest diameter) indicates directly the flow volume on the
graduated tube scale.
The conical graduated tube is equipped as standard with a
measuring range scale in l/h - from DFM 350 onwards also in %
- for water at 20°C . It has external V-way strips with 2 movable
set-point indicators for the optimum marking of minimum and
maximum flow volume or for accomodating limit signal
transmitters. In the measuring tube the float is located, of PVDF
as standard as well as the float trap. From DFM 350 onwards
two are provided, one at the top and one at the bottom. For
automatic measurement, the float is equipped with an
ambedded magnet insert which is liquid-proof. |
