The LF19B1 series balanced orifice plate flowmeter is a typical differential-pressure flowmeter, designed for use in conjunction with transmitters and display instruments (or control units). It enables precise measurement of fluid flow and is widely adopted across various industrial sectors due to its simple structure, convenient installation, and reliable operational performance. Orifice plate flowmeters boast a long history of practical application, backed by extensive experimental data. Their design and manufacturing processes have already been standardized, eliminating the need for actual-flow calibration. Moreover, these flowmeters can handle a wide variety of measured media, accommodate diverse pipe diameters, and operate effectively at temperatures as high as 550°C—and even withstand pressures up to 32 MPa. As such, they remain one of the primary instruments used for flow measurement in industrial automation and control processes. This product features the following key characteristics: <br/> ● The structure is easy to replicate, simple yet sturdy, with stable and reliable performance, and at an affordable price. <br/> ● Widely applicable, covering single-phase fluids (liquid, gas, steam), as well as partially immiscible flows. Products are available for pipe diameters and operating conditions—such as temperature and pressure—commonly encountered in industrial processes. Moreover, throttling devices, differential pressure transmitters, and display instruments can be manufactured separately by different suppliers, making large-scale production more convenient. <br/> ●The annular chamber and drilled holes enhance measurement accuracy while reducing the minimum required straight pipe length for installation. <br/> ● In addition to its online, dynamic full-compensation function, the intelligent orifice flowmeter also features self-diagnosis and automatic range setting. <br/>
The LF-19B2 series of vane-type flowmeters builds upon the traditional isolated-diaphragm target flowmeter by integrating a new strain sensor into the target design. At the same time, it leverages the latest digital and microelectronic technologies to process the detected sensor signals into a 4–20mA output proportional to the flow rate. The instrument also features dual-row large LCD displays that simultaneously show both instantaneous and cumulative flow rates, significantly enhancing both the structural design and performance of conventional target flowmeters. This model is particularly well-suited for measuring complex fluids with high viscosity, low Reynolds numbers, or those containing suspended particles. Key features of this product include: <br/> ● High-temperature and high-pressure resistance: Ranges from -80°C to +200°C, with pressure capacity up to 10 MPa <br/> ● Suitable for various diameters: φ15–φ1500mm <br/> ● Suitable for measuring highly viscous media containing sediment and sand <br/> ● Multiple installation options available: clamp-type, flange-type, threaded-type, insertion-type, detachable insertion-type, sanitary-type, and integrated/segmented designs. <br/>
