Failure-Free Operation for 5 Years, Jiwei Tuning Fork Liquid Level Switches Favored by Customer

204 pieces of Jiwei Flame-proof Tuning Fork Liquid Level Switches have been operating stably and reliably in Tenglong Aromatic Hydrocarbon (Zhangzhou) Co., Ltd. for more than 5 years without any problems or failures. The durable quality and excellent performance are beyond the user’s expectations and strongly preferred by the user.

In fact, the customer has made rigorous comparisons on the performance indexes of tuning fork liquid level switches between instrument peers at home and abroad.

The level controls of sealed white oil tank in the pump are momentous to prevent petrochemical leakages or other safety accidents. Thus the extremely high requirements put forward on the reliability and qualifications of the instrument with the prerequisite of flame-proof function.

However, other than imported instrument, customer found that the quality and performance indexes of Jiwei Tuning Fork Liquid Level Switch are competitive. Specifically, the tines are with compact design in the length of 40mm only, which is especially suitable for pipeline measurement; the precisely pre-adjusted harmonic resonant frequency of fork ensures its high sensitivity; the strong disturbance resistance ability makes Ring-11 not influenced by foam, bubbles, viscosity, vibration and other extreme working condition. The qualifications of SIL2 / SIL3 Functional Safety Assessment, as well as both Intrinsic Safety (Ex ia IIC T6~T1 Ga) and Flame-proof Enclosure (Ex d IIC T6~T1 Gb) make Ring-11 more reliable and effective to solve the problem of high-pressure and low-density liquid measurement in explosion-proof occasions, which is suitable for liquid level controls in the fields of PetroChina and Sinopec.
