| PURPOSE:To prevent the influences of temperature or pressure fluctuations by forming a tuning fork structure of U-shaped tube through which a fluid to be measured flows and a support beam equipped with a magnet on the tip, and exciting with an electromagnetic force and converting in terms of electric quantity with the help of a strain gauge. CONSTITUTION:A permanent magnet 2 of U-shaped tube 1 facing an electromagnet 4 is excited to a proper oscillation number of this system with the assistance of said electromagnet generating an electromagnetic force, so that a fluid running through the U-shaped tube is caused to generate a Coriolis force. Said Coriolis force has a varying magnitude proportional to the mass of a fluid, and the direction of the force coincides with a direction of motion and a direction of the vector product of an angular velocity exciting the U-shaped tube. Since the direction of a fluid is reversed at the input and output side of the U-shaped tube, a twisting torque is generated in the U-shaped tube on account of the Coriolis force on the both legs side. This oscillation torque is proportional to the mass flow of a fluid, and is transferred to a torque beam 6 and then is converted in terms of electric quantity by means of four pieces of strain gauge attached on the beam surface, thus enabling the output proportional to a mass flow to be available. Under this constitution, it is possible to prevent the influence of temperature and pressure fluctuations. | ||||||

| PURPOSE: A low loss orifice flowmeter is provided to minimize pressure loss, and to optimize efficiency for measuring flow rate. CONSTITUTION: An orifice flowmeter comprises an orifice(5) for measuring flow rate of an upstream side, and a diffuser(7). A thin orifice plate(1) is installed in the orifice to be fixed between flanges(3) of a pipe. A piece(6) is placed on a downstream part of the orifice, which is connected with the cylindrical diffuser to variably move an inlet and an outlet of the orifice and the diffuser. Pressure tabs are installed on front and rear portion of the orifice plate to be used for measuring pressure inside the orifice. The diffuser forms a channel on the downstream part of the orifice plate to solve flow separation generated on the downstream of the orifice plate, to minimize pressure loss, and to reduce loss coefficient of the orifice so as to get optimum efficiency of measurement of flow rate depending on flowing condition in the orifice. Loss in the orifice is reduced by the diffuser as the diffuser reduces an axial flow part formed on the downstream part of the orifice plate. | ||||||
