Intelligent dual flange liquid level transmitter

1WRS3351DPIntelligent dual flange liquid level transmitterIntroduction
Used to prevent the medium in the pipeline from directly entering the transmitter, the pressure sensing diaphragm is connected to the transmitter by a capillary tube filled with fluid. It is used to measure the liquid level, flow rate, and pressure of liquids, gases, or vapors, and then convert them into 4-20mA DC signal output. After the WRS3351DP remote transmission flange differential pressure transmitter is equipped with a remote transmission sealing device, it becomes the WRS3351DP double flange differential pressure transmitter, which can be used for measuring pressure, differential pressure, and liquid level. It can communicate with the HART handheld device for setting and monitoring.

IIWRS3351DPIntelligent dual flange liquid level transmitterSuitable occasions
Can eliminate the occurrence of pressure pipe leakage and pollution of the surrounding environment; It can avoid the tedious work of frequently replenishing isolation fluid due to the instability of measurement signals when using isolation fluid. Applicable to the following measurement and control situations:
1. Viscous media at high temperatures;
2. Medium that is prone to crystallization;
3. Settling media with solid particles or suspended solids;
4. Highly corrosive or toxic media.

3、 Product Features
1. Simulate "online operation" assessment for each transmitter to ensure stable and reliable operation under extreme environmental temperature, medium temperature, and working pressure (including positive pressure or vacuum);
2. Adopting a "dynamic profile" remote transmission membrane structure, the membrane will not be damaged after overload; The accuracy will not change after long-term work;
3. The occurrence of oil leakage was investigated by using a filling system with full fusion welding and rigid sealing structure;
4. A novel capillary coupling component is designed to provide reliable protection for the capillary, making it less prone to breakage during on-site use;
5. A variety of remote transmission devices in terms of variety, form, and size, as well as a rich variety of filling fluids, can meet the measurement needs of various occasions;
6. We can provide various special needs products, including high temperature, high vacuum, fast response, and unequal long capillary (difference ≤ 4.5 meters) remote differential pressure transmitters.
