Differential pressure flowmeter with upstream pressure tap located at a distance of D from the upstream face of the orifice plate and downstream pressure tap located at a distance of 0.5D from the upstream face of the orifice plate.

The monoblock diaphragm and the ISA1932 monoblock nozzle are made from a solid round. The pressure taps are directly machined in the monoblock. They can be simply machined (pressure tapping holes) or supplied with nipples to connect directly to your installation. This type of diaphragm or nozzle has the advantage of being simple to install: simply mount it between single flanges or weld directly on the pipe for a version to be welded. All types of edges (sharp-edge, conical, quarter-circle, eccentric, segmental and multi-hole) can be made in a single-piece version. Flanged or corner pressure taps can be made in monoblock version.

Flow glass to insert in a piping to check the circulation of the fluid

The annular chamber (carrier rings) is proposed for orifice plates, for venturis and for nozzles. It has several advantages: it favors the circulation of the fluid over the complete circumference of the pipework and offers a more stable and precise averaged pressure; in the case of the orifice plate, it also allows to change only the plate in case of maintenance or change of process compared to a monoblock where the complete system must be changed. This type of mounting is particularly recommended for pipe diameters smaller than DN50.

The 1''/1'' flowmeter is also called a flowmeter with flange pressure taps. The high pressure upstream measurement is 1 inch from the upstream edge of the plate and, symmetrically, the low pressure measurement is 1 inch from the downstream edge of the plate. This is often a pre-assembled complete set with orifice plate mounted between orifice flanges. Orifice flanges are standardized and manufactured to ASME B16.36. The orifice plate is manufactured in accordance with ISO 5167 or ASME MFC-3M.

According to ISO 5167, flowmeters with orifice plates and nozzles (long radius) can benefit from D - D/2 mounting. This corresponds to a positioning of the upstream tap at a distance of 1D (D, internal diameter of the pipework) from the upstream of the orifice plate and the downstream tap at a distance of 1/2D from the downstream of the plate. This type of assembly has the advantage of not requiring orifice flanges (more expensive than standard flanges): you simply prepare bosses on the piping upstream and downstream of the measurement to position the pressure taps. It is widely used for large pipe diameters.

Actor in the field of instrumentation, Deltafluid offers measurement products in pyrometry. Our range includes thermometers to obtain direct indications of temperature but also temperature sensors (resistance probe, thermocouple, multi-point probe, pyrometer assembly ...) which can be coupled with transmitters.
