Its density measurement precision of \u00b10.1 kg\/m\u00b3 makes it an elite tool for quality control and custody transfer where every drop and decimal point impacts the bottom line.<\/p>\n<\/li>\n<li>\n<p data-path-to-node=\"3,1,0\">Optimized Performance for Entrained Gas (MFT): Liquids containing air or gas bubbles traditionally cause significant errors in Coriolis meters. The Promass Q utilizes Multi-Frequency Technology (MFT) to actively compensate for these effects in real-time, ensuring reliable and continuous measurement even in aerated fluids or viscous liquids with gas pockets.<\/p>\n<\/li>\n<li>\n<p data-path-to-node=\"3,2,0\">Low Pressure Loss and High Turndown: The sensor&#8217;s unique design minimizes pressure drop across the meter. This allows for a wider usable flow range (high turndown) and reduced energy costs for pumping, while also maintaining a stable zero point for long-term reliability.<\/p>\n<\/li>\n<li>\n<p data-path-to-node=\"3,3,0\">Heartbeat Technology for Documented Safety: Integrated Heartbeat Technology provides continuous internal diagnostics and documented verification without interrupting the process. This enables operators to verify the meter\u2019s high-precision performance and maintain audit trails for regulatory and fiscal compliance effortlessly.<\/p>\n<\/li>\n<li>\n<p data-path-to-node=\"3,4,0\">Versatile System Integration and WLAN Access: The Proline 300 transmitter features a compact dual-compartment housing with up to 3 freely combinable I\/Os. Its backlit touch display and WLAN access allow for wireless commissioning and operation, enabling technicians to interact with the device from a safe distance or without opening the enclosure.<\/p>\n<\/li>\n<li>\n<p data-path-to-node=\"3,5,0\">Multivariable Measurement and Compact Footprint: By providing simultaneous data for mass flow, volume flow, density, and temperature, the Promass Q 300 eliminates the need for multiple discrete sensors. Its ability to operate without straight inlet or outlet piping runs allows for significant space savings in dense metering skids.<\/p>\n<\/li>\n<\/ul>\n<hr data-path-to-node=\"4\" \/>\n<h4 data-path-to-node=\"5\">\u041e\u0441\u043d\u043e\u0432\u043d\u044b\u0435 \u0442\u0435\u0445\u043d\u0438\u0447\u0435\u0441\u043a\u0438\u0435 \u0445\u0430\u0440\u0430\u043a\u0442\u0435\u0440\u0438\u0441\u0442\u0438\u043a\u0438 \u0443\u0441\u0442\u0440\u043e\u0439\u0441\u0442\u0432\u0430<\/h4>\n<table data-path-to-node=\"6\">\n<thead>\n<tr>\n<td><strong>\u041e\u0441\u043e\u0431\u0435\u043d\u043d\u043e\u0441\u0442\u044c<\/strong><\/td>\n<td><strong>\u0422\u0435\u0445\u043d\u0438\u0447\u0435\u0441\u043a\u0438\u0435 \u0445\u0430\u0440\u0430\u043a\u0442\u0435\u0440\u0438\u0441\u0442\u0438\u043a\u0438<\/strong><\/td>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td><span data-path-to-node=\"6,1,0,0\">\u041e\u0448\u0438\u0431\u043a\u0430 \u043c\u0430\u0441\u0441\u043e\u0432\u043e\u0433\u043e\/\u043e\u0431\u044a\u0435\u043c\u043d\u043e\u0433\u043e \u0440\u0430\u0441\u0445\u043e\u0434\u0430<\/span><\/td>\n<td><span data-path-to-node=\"6,1,1,0\">\u00b10,05% (PremiumCal) \u0438\u043b\u0438 \u00b10,1%<\/span><\/td>\n<\/tr>\n<tr>\n<td><span data-path-to-node=\"6,2,0,0\">\u041f\u043e\u0433\u0440\u0435\u0448\u043d\u043e\u0441\u0442\u044c \u0438\u0437\u043c\u0435\u0440\u0435\u043d\u0438\u044f \u043f\u043b\u043e\u0442\u043d\u043e\u0441\u0442\u0438<\/span><\/td>\n<td><span data-path-to-node=\"6,2,1,0\">\u00b10,1 \u043a\u0433\/\u043c\u00b3 (\u043e\u043f\u0446\u0438\u043e\u043d\u0430\u043b\u044c\u043d\u043e) \u0438\u043b\u0438 \u00b10,5 \u043a\u0433\/\u043c\u00b3<\/span><\/td>\n<\/tr>\n<tr>\n<td><span data-path-to-node=\"6,3,0,0\">\u041d\u043e\u043c\u0438\u043d\u0430\u043b\u044c\u043d\u044b\u0439 \u0434\u0438\u0430\u043c\u0435\u0442\u0440<\/span><\/td>\n<td><span data-path-to-node=\"6,3,1,0\">DN 25\u2013100 (1\u20134 \u0434\u044e\u0439\u043c\u0430)<\/span><\/td>\n<\/tr>\n<tr>\n<td><span data-path-to-node=\"6,4,0,0\">\u041a\u043e\u0440\u043f\u0443\u0441 \u043f\u0435\u0440\u0435\u0434\u0430\u0442\u0447\u0438\u043a\u0430<\/span><\/td>\n<td><span data-path-to-node=\"6,4,1,0\">Compact dual-compartment with WLAN<\/span><\/td>\n<\/tr>\n<tr>\n<td><span data-path-to-node=\"6,5,0,0\">\u041f\u043e\u0434\u043a\u043b\u044e\u0447\u0435\u043d\u0438\u0435<\/span><\/td>\n<td><span data-path-to-node=\"6,5,1,0\">EtherNet\/IP, PROFINET, Modbus RS485, 4-20mA HART<\/span><\/td>\n<\/tr>\n<tr>\n<td><span data-path-to-node=\"6,6,0,0\">\u0421\u043f\u0435\u0446\u0438\u0430\u043b\u044c\u043d\u044b\u0435 \u0442\u0435\u0445\u043d\u043e\u043b\u043e\u0433\u0438\u0438<\/span><\/td>\n<td><span data-path-to-node=\"6,6,1,0\">\u041c\u043d\u043e\u0433\u043e\u0447\u0430\u0441\u0442\u043e\u0442\u043d\u0430\u044f \u0442\u0435\u0445\u043d\u043e\u043b\u043e\u0433\u0438\u044f (\u041c\u0427\u0422)<\/span><\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<hr data-path-to-node=\"7\" \/>\n<h5 data-path-to-node=\"8\">\u041e\u0431\u043b\u0430\u0441\u0442\u044c \u043f\u0440\u0438\u043c\u0435\u043d\u0435\u043d\u0438\u044f<\/h5>\n<ul data-path-to-node=\"9\">\n<li>\n<p data-path-to-node=\"9,0,0\">Custody Transfer: The primary choice for fiscal measurement of oils, fuels, and high-value chemicals where extreme accuracy is legally required.<\/p>\n<\/li>\n<li>\n<p data-path-to-node=\"9,1,0\">Aerated Liquid Applications: Measuring liquids that naturally contain or trap gas, such as ice cream, adhesives, or oils during tank unloading.<\/p>\n<\/li>\n<li>\n<p data-path-to-node=\"9,2,0\">High-Precision Density Measurement: Used in blending or concentration control where minute changes in density indicate a change in product quality.<\/p>\n<\/li>\n<li>\n<p data-path-to-node=\"9,3,0\">Loading and Unloading: Ideal for bunkering or tank truck loading where the presence of air is common at the beginning or end of a transfer.<\/p>\n<\/li>\n<\/ul>","protected":false},"excerpt":{"rendered":"<p>The Proline Promass Q 300 is the industry benchmark for applications requiring the absolute highest measurement accuracy for mass flow, volume flow, and density.
