Electronic Output Transmitter

Liquid Level Transmitters are built to transmit a specific electrical output depending on the presence of fluids and liquid level within a process tank or vessel. Level Transmitters are available in three different sensing technologies depending on the intended industrial application.

Visual Level Indicators
Magnetic Float Tank Level Indicators

Visual Level Indicators, or more commonly known as magnetic level indicators are designed to provide a visual indication of the media level within a tank or vessel. Visual level indicators or VLI's are passive devices, requiring no electrical power to visually project the level information. The VLI or Visual Level Indicator is attached to a liquid process vessel or process tank via the top, bottom and/or side mounted connections. The mounting connections allow liquid level equalization to take place between the tank and the level indication device. The magnetic float switch that is contained within the indicator's chamber fluctuates according to the tank's liquid level and actuates colored indicator flags, producing an accurate visual level representation.
