Pressure measurement - Import export

Different types of pressure transmitters exist: differential pressure transmitter for measuring a pressure difference ΔP but also a relative or absolute pressure transmitter. For more specific applications, it will be necessary to use: a differential pressure transmitter to correct variations of pressure and temperature of a gas two transmitters for the same differential pressure flow element to increase the measuring range For more details on these cases, please see the Frequently Asked Questions tab on this page.

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.

Continuous flow measurement of powder or granules in high pressure densephase conveying. Designed to measure solid flows during pneumatic dense phase transport. The sensor measures density and speed. • pressureresistant up to 64 bar • maintenancefree • contactless • ATEX category 3 approved

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.

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.

Suitable for flow measurement in large pipes, for installations with low pressure dropAverage measurement over the entire length of the tube. Installation on the pipe: compression fitting, flange ISO PN 2.5 to 420 or ASME 150 # to 2500 #, retractable. Material: Standard: 304L / 316L stainless steel, others according to your application.

Oxygen partial pressure measurement Brand : SETNAG ADVANTAGES Wide measurement range: from 10 -35 to 0.25atm. Excellent response time thanks to the MicroPoas® miniaturized zirconia sensor. Easy and fast set-up MEASUREMENT AND WORKING TECHNIQUE The reactional mixture to be analysed freely circulates through the analyser, and the MicroPoas® delivers a signal which reflects the equilibrium oxygen partial pressure in the gas. Jok’Air-2060 can measure from 10 -35 to 0.25atm. EXAMPLES OF APPLICATIONS Materials characterization Nuclear research
