Product Introduction of Transformer Oil Level Gauge
Overview
Transformer oil level gauge is an essential accessory matched with oil conservator of oil-immersed transformers. It visually monitors the liquid level of insulating oil inside the tank in real time, helping staff detect oil leakage, oil shortage or overfilling quickly. Models with alarm contacts can send out warning signals when oil level is too high or too low, widely applied in power transformers, box substations and reactors.
Two mainstream types: magnetic float pointer oil level gauge (YZF/UZF series for large main transformers) and tubular sight oil level gauge (YWZ series for small transformers & hydraulic tanks).
Structure
- Stainless steel float: floats up and down with oil surface, corrosion resistant;
- Magnetic transmission: non-contact magnetic drive, zero oil leakage, good tightness;
- Clear dial scale: standard high/low oil level marking, easy outdoor reading;
- Optional alarm switch: dual limit alarm for remote monitoring system;
- Standard flange base: universal mounting for most oil conservators.
Advantages
- Excellent sealing performance, resistant to transformer oil, high & low temperature;
- Maintenance-free magnetic structure, low failure rate, long service life;
- High visibility dial, readable under strong sunlight outdoors;
- Customizable alarm signal output for unattended power station;
- Multiple ranges available, custom flange size acceptable;
- Weatherproof & anti-corrosion, suitable for long-term outdoor operation.
Application
Oil immersed distribution transformer, 35kV/110kV power main transformer, box substation, reactor, hydraulic cooling oil tank and other industrial oil storage equipment.
Main Models
- Float type oil level gauge: YZF1-100, YZF1-140, UZF200, UZF250
- Tubular sight gauge with thermometer: YWZ-80, YWZ-100, YWZ-125
