Christine DELPAL, la créatrice de Karawan, a conçu cette collection en référence aux malas, ces bracelets de prière tibétains, égrenés par les bouddhistes. Les chaînettes en chapelet sont façonnées à la main par les joaillers de Jaïpur. Elle revisite la tradition en les parsemant de pierres fines facetées et de perles d’argent ou or frappées de motifs indiens.Une collection pour sublimer les pierres fines, Quartz fumé, Cornaline, Labradorite, Onyx vert, Aqua Chalcy et pierre de lune sur monture argent 925 plaqué or 3 µ façonnée à la main

Orifices: dimensioned according to the fluid, the pressure drop or the flow to be achieved going through the restriction.
Plate thickness: calculated taking into account the pressure drop generated by the plate and the diameter of the pipework in order to avoid a deformation of the plate. For more details, see our Frequently Asked Questions.
Noise: the number of orifices is determined according to the level of noise not to be exceeded.
The maximum noise level depends on the operating conditions: limited to 85 dB(A) by the regulatory body for an average daily exposure in continuous operation. Intermittent or emergency operation - acceptable upper values (see corresponding regulations).
If the noise level is still too high, it is possible to switch to a multi-stage restriction orifice.
Cavitation: the cavitation level is checked for each plate and the orifices are calculated to avoid cavitation. For more information on cavitation, see our Frequently Asked Questions.

The nozzle has a radiated input and is therefore suitable for fluids flowing at high speed. Unlike an orifice plate whose edge could be damaged, the ISA 1932 nozzle and the long radius nozzle according to the names of the standard are quite suitable for these applications.
For corrosive or aggressive fluids, the surface in contact with the fluid can be covered with a special coating to improve their lifetime.
A spectacle blind consists of a spade and a spacer which are manufactured for the purpose of installation in one piece. It is used as a safety device to isolate a particular section of pipe or equipment when this section or this equipment is to be inspected or decommissioned. It is different from a valve in the sense that the obturator is considered an isolation device.
Depending on the size and class of flanges, it will be more suitable to offer two separate components (spade and spacer) instead of a spectacle blind to limit weight and avoid handling heavy parts.

The venturi tube has a convergent inlet, a throat and a divergent outlet. It is a differential pressure flow meter well known to create a low permanent pressure drop; thus, it is suitable for measuring, for example, a low pressure flow rate. More over, it requires short upstream and downstream straight lengths.
There are different types of venturi tubes : the machined venturi made from a solid round for small size parts, the rolled welded venturi made from sheet metal for larger pieces up to 1200 mm diameter and the venturi "as cast" allowing a better accuracy up to 800 mm diameter.

== Description =====================
The thin case in women's silver watches is one of the most popular European trends. The original design of the lugs with three slender rows of cubic zirconias deserves special attention. Guilloche dials with textured indexes are available in three colors: navy blue, black and white.
Orifice plates or diaphragms are the most commonly used primary elements for differential pressure flow measurement. They allow measurement over a wide range of flow rates and for a wide range of pipe diameters. There are several types: the sharp-edge orifice plate, the best known, the other concentric plates with conical inlet and quarter circle plate for the measurement of low flows or viscous fluids and the eccentric plate or segmental plate for the measuring dirty or impure fluids. Finally, the multi-hole / conditioning orifice plate allows a measure of quality while providing a minimum footprint.
Inserted within a circular pipe, they create an obstacle, increase the speed of the fluid and generate a pressure difference between upstream and downstream of the restriction. This differential pressure measurement is proprotional to the flow rate value.

The sonic state of the nozzle means that the flow reaches the speed of sound when going through the throat. Under these conditions, the flow rate depends mainly on the upstream pressure and the fluid temperature. This makes it possible to deliver a stable and perfectly known flow, independent of the downstream pressure conditions of the nozzle. This nozzle is thus used to provide a standard flow value when it comes to calibrating another type of flow meter.
