Product Description
HQ1151/3051/3351/3851 Flange Level Transmitter
| Product Detail |
HQ1151/3051/3351/3851Detailed introduction of flange level transmitter products: |
|
The key raw materials, components, and parts of the HQ1151/3051/3351/3851LT-Y flange level transmitter are all imported or sourced from joint ventures. The entire unit undergoes rigorous assembly and testing. This product features advanced design principles, a complete range of specifications, and ease of installation and use. Because its appearance fully integrates the structural advantages of the two most popular and widely used transmitters in China (Rosemount 3051 and Yokogawa EJA), it offers users a refreshing experience. Furthermore, it is directly interchangeable with traditional series products in terms of installation, demonstrating strong versatility and substitutability. To adapt to the continuous improvement and development of automation levels in China, this series of products, in addition to its compact and exquisite design, also features intelligent functions with the HART fieldbus protocol. The 1151/3051LT flange level transmitter can accurately measure the level and density of various containers. It is available with flat flanges and insertion flanges, in 3-inch or 4-inch sizes, and in 1501b and 3001b specifications. Custom flanges are also available upon request. Flange diaphragm materials are optional.
