One Product Overview
HR-3351/1151LT typeflangedLevel transmitterOur company has introduced advanced technology and equipment from abroad to produce a new type of transmitter. The key raw materials, components, and parts are all imported, and the entire machine has undergone strict assembly and testingFlange type liquid level transmitterIt has the characteristics of advanced design principles, complete varieties and specifications, and easy installation and use. Due to the complete integration of the structural advantages of the two most popular and widely used transmitters (Rosemount 3051 and Yokogawa EJA) in the appearance of this model, users have a refreshing feeling. At the same time, it can be directly replaced with traditional series products in installation, with strong versatility and substitution ability. To adapt to the continuous improvement and development of domestic automation level,Flange type liquid level transmitterIn addition to its compact and exquisite design, it also introduces intelligent features with the HART fieldbus protocol.

RF-1151/3351LT flange type liquid level transmitter can accurately measure the liquid level and density of various containers. There are flat flanges and plug-in flanges to choose from, with flanges of 3 inches or 4 inches and specifications of 1501b and 3001b. The flange can also be customized according to the user, and the flange membrane sheet material is optional. Please consult the sales department or refer to our company's relevant sample books for specific dimensions.
Measurement range:
Differential pressure: 0-6.2-690KPa
Static pressure: 2.5MPa
