YWJ double-bellows level gauge


Due to its excellent quality, fine workmanship and outstanding performance, our product has made significant improvements in solving the problems of leakage, dropping, inlet fogging, imprecision and durability etc.

Type tests and full-performance tests conducted by China Institute of Measurement and Testing Technology and other authoritative institutions have shown that the overall performance our product has exceeded that of similar domestic products and reached the international advanced level.

Our Advantages：

• All components and parts of our level gauge are manufactured by our company, to ensure the quality of materials for components and parts.
• Mechanical precision assembly is adopted to reduce the error between components and parts and thus ensure the precision and durability of our level gauge.
• Our level gauge can precisely measure the level in the tank from outside, without contacting the liquid and gas inside the tank, and has truly realized isolation measurement.
• Damping device is installed，with damping time adjustable, which also applies to measurement of pulsation flow with high amplitude and high frequency.
• Single-track overload protection device is installed within our product, which will cut off the flow of filling liquid between high-pressure and low-pressure bellows in case of single-track overload, thus protecting measuring units from being damaged.
• Our level gauge can be used separately to measure differential pressure, pressure and level etc.
• Our product adopts Anti-corrosion isolation measures and can be used in harsh conditions or for measuring the flow of corrosive medium.

Safe——With measuring head and instrument installed outside the container, our level gauge will not contact liquid and gas inside the tank during installing, repair and maintenance and thus safety is secured when measuring toxic, corrosive, pressured, flammable and combustible, volatile, easy-to-leak liquid. Even when instrument is damaged or in maintenance, there is still absolutely no possibility of leakage.

Environment-friendly——Our level gauge truly realizes isolation measurement, without any contact with the measured medium, which ensures no possibility of liquid and gas, thus protecting the environment.

Convenient and economical——Online maintenance is provided for our level gauge without stopping production, meanwhile installing and maintenance becomes more economical and convenient when there is no need to open holes on container or use flange plate and communication pipe.

Durable and reliable——Measuring head and instrument contain no mechanical motion parts and are sealed tightly from outside, thus avoiding abrasion or corrosion while leading to increased durability and minimal maintenance.
