YZF2-140TH Oil Level Gauge

YZ series pointer type for transformeroil level meter(referred to as oil level meter) is the transformer oil storage cabinet oil level test device. Its main structure includes: feeling mechanism (float, pendulum), transmission mechanism, magnetic coupler, indicating mechanism, alarm mechanism. Feeling mechanism will be the oil level through the transmission mechanism feedback to the magnetic coupler, and drive the indication mechanism, through the pointer on the dial to indicate the oil level, and finally in the oil level of the highest and lowest alarm signal, play the role of remote monitoring.

• model number: YZF2-140TH
• typology: Pointer oil level gauge.
• use: Mainly used for oil level indication in power transformer oil storage cabinets

Installation and use

1 Inspection

After connecting the float to the pendulum (float section) first, do the following checks:

a. Check for loose pointers and flexible rotation.

b. Check the lowest and highest point indication, when the float pendulum respectively in the lowest and highest position, the pointer should be respectively in the red area should be alarmed (such as purchased products for high and low oil level alarm should also be alarmed in the area).

c. Check dial glass for damage.

d. Check float for damage.

e. Check that the pendulum is securely attached to the float and to the drive section.

2 Installation

When installing, first extend the float part into the oil storage cabinet, and then fasten the oil level gauge to the mounting flange with bolts. The mounting flange is provided by the user.

Maintenance and Precautions

Since this oil level meter is a precision instrument, it is not allowed to be disassembled or installed without special reasons. Once a failure occurs, you should contact the manufacturer in time.

Caveats:

a. Check this oil level timer and do not hit its transmission part violently.

b. This oil level gauge is not suitable for places where the surrounding environment has violent vibrations and bumps, and is not easily subjected to strong impact.

c. The liquid level measured by this oil level gauge is also less likely to fluctuate violently.

d. When the oil level gauge is transported as a unit with the oil storage cabinet, the float section should be secured (preferably installed on site).
