Pressure plates - Import export

The conservatory market has been changing over several years ; a conservatory is now considered as a real living room integrated to the house, and usable all year long. With NOVATOIT ® brand, AV Composites completely revolutionized the conservatory market offering innovative and technical solutions in order to answer different issues. NOVATOIT ® includes all the panels from the scope of the conservatory having a constant need for technical solutions to improve the thermal performance, acoustic and esthetic.

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.

Orifice diameter: dimensioned according to the fluid, to the pressure drop to be achieved and to the flow going through the restriction. Plate thickness: calculated taking into account the pressure drop generated by the plate and the diameter of the pipework to prevent plate deformation. See more details in our Frequently Asked Questions. Noise: control of the estimated noise level at 1 m. In case of high noise level, refer to the multi-hole plate. Cavitation: The cavitation level is checked for each plate. In the presence of cavitation, a multi-stage restriction orifice alternative may be proposed depending on the operating conditions of the restriction. For more information on cavitation, see our Frequently Asked Questions. Critical flow or choked flow: if the fluid reaches its maximum speed when passing the restriction, its flow can not increase. A multistage solution can be proposed depending on the operating conditions of the restriction. For more information on critical flow

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.
