The combination of a Coriolis mass flow meter, dual valve pressure controller (PCD), and dome-loaded back pressure regulator (BPR) enables automatic flow control under the following conditions:<\/p>\n<ul>\n<li><span style=\"color: #000000;\">Systems flowing fluids that are aggressive or of unknown composition<\/span><\/li>\n<li><span style=\"color: #000000;\">High operating pressures where typical control valves are not rated<\/span><\/li>\n<li><span style=\"color: #000000;\">A wide range of flow rates<\/span><\/li>\n<\/ul>\n<p>This fully automated system provides the added bonus of digital data collection for improved process control and evaluation.<\/p>\n<h2>How it works<\/h2>\n<ol>\n<li>The CODA Coriolis meter sends an analog flow signal to the PCD.<\/li>\n<li>PCD firmware translates the flow signal into a pressure setpoint<\/li>\n<li>This raises or lowers the pressure in the dome-loaded BPR to achieve the desired flow rate.<\/li>\n<\/ol>\n<p><iframe title=\"Alicat Instruments: Application - Backpressure Control\" width=\"1080\" height=\"608\" src=\"https:\/\/www.youtube.com\/embed\/9BvYOSnGZcc?feature=oembed&rel=0\"  allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" allowfullscreen><\/iframe><\/p>\n<h2>Benefits of controlling flow with this setup<\/h2>\n<p>This setup is beneficial in applications with fluids which are aggressive or of unknown composition and require highly resistant wetted materials. It also works for fluids with unique properties which behave adversely when traditional control methods are deployed, such as solidification under mechanical shear. Use this setup even in systems operating at high pressures and across wide flow ranges.<\/p>\n<p>Custom firmware on the PCD makes it simple to convert analog flow signals into pressure setpoints that change pressure levels in the BPR to adjust flow rate. The front panel screen on the PCD enables the user to easily regulate flow rate without the need for a PLC.<\/p>[\/et_pb_text][\/et_pb_column][\/et_pb_row][\/et_pb_section]\n","protected":false},"featured_media":46458,"parent":0,"template":"","meta":{"_acf_changed":false,"_et_pb_use_builder":"on","_et_pb_old_content":"","_et_gb_content_width":"1920","content-type":"","_searchwp_excluded":""},"categories":[],"class_list":["post-38375","support","type-support","status-publish","has-post-thumbnail","hentry"],"acf":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO Premium plugin v27.3 (Yoast SEO v27.3) -
