Cone meters work on the well-known Δp principle and are used for measurement of fluid flow. Because of the specific shape of this primary element they require very short straight lengths of pipes before and after the element.

Orifices plates are used for measurement of fluid flow. Measurement is done by the Δp principle. The orifice plate is still widely used in the industry because of its simplicity and reliable performance.

Meter run assembly is made out of stainless steel and it’s components are an orifice plate and the needed straight lengths before and after the orifice plate. This construction expands the field of use of the orifice plate.

Nozzles are used for measurement of fluid flow. In comparison with orifice plates the nozzle makes less of a permanent pressure loss and they have a longer service life.

These types of plates are used when there is a requirement to reduce the process line pressure or to restrict the flow to a pre-defined value regardless of the downstream pressure.

Venturi tubes are used for measurement of fluid flow. With its angled inlet and outlet cones which help control the pressure recovery, the venturi tube is the most efficient of all the differential meters available.

PLC blocks are blocks that realize specific functions such as:

• Flow correction when Δp principle is used (flow of water, steam, natural gas…)
• Flow correction when Vortex, Electromagnetic, Ultrasound or Turbine flow meters are used
• Calculation of delivered heat energy
• Calculation of density, enthalpy…
