Testimonial- “They are perfect so far, our guys sure do like them!” – Don (Maintenance Supervisor – Texas USA)
Our battery water level indicators made their chore of checking electrolyte levels much easier. They liked them so much, they recently ordered 200 more. They installed the water level indicators on backup battery arrays in their oil refinery to ensure that correct water levels are always maintained.
Battery Water Level Indicator Installation Example
The picture below shows our battery water level indicators that were installed at the Texas refinery mentioned above. This particular set of batteries provide backup power to critical oil pumps that supply oil to their 40 MW generators. In the event that one of these generators experiences a loss of primary power, shaft damage can occur as a result of a lack of oil during the time it takes for the generator to coast to a complete stop. This will allow the oil pumps additional time to keep the generators supplied with oil until primary power has been restored.
Prior to installing the battery water level indicators, it was a time-consuming task to verify whether the battery water levels were within the acceptable tolerance or not. After installing the indicators, the water levels of each battery could be instantly seen because the red indicator in the sight glass can be viewed from any angle. Not only did this save their maintenance workers much time and effort, but it also ensured that each battery contained an acceptable level of electrolyte to prevent damage and the possibility of battery failure.
Battery Water Level Indicator Benefits
- Easy to use and see.
A mechanical float with a red tip is easy to see in the vertical sight glass.
- Patented Technology
The VMV with Water Miser™ technology will reduce the water loss in the battery cell.
- Easy Installation
The bayonet 1/4 turn installation will ensure a correct fit into the cell.
The flame arrestors will prevent any external spark from entering the cell.
A large problem with battery maintenance is the uncertainty of knowing when to fill batteries with water. Without indication, operators often need to devise watering schedules or carry out periodic inspections to maintain the batteries. With our Battery Water Level Indicator, the guesswork of when to add water is gone. No schedules are needed and less time is wasted. The red and green indicator ensures that mistakes are not made by operators so that your batteries are always properly watered.
Several models are currently available to accommodate various water level specifications for different batteries. The chart shown below is for general reference only, and should not be relied on to determine which water level indicator will fit on your battery. Please measure your battery before ordering by following the instructions below.

Please measure your battery before ordering by following these steps. Remember to wear protective clothing, gloves, and goggles. 1) Make sure the water level in the battery is full per the battery manufacturers recommended fill level. For most lead-acid batteries, the water fill level is 1/4″ below the bottom edge of the battery vent well. 2) Measure the distance between the electrolyte and the top surface of the battery where the vent cap sits on. Then locate the model number in the chart above that corresponds to the water fill level dimension of your battery.

Electronic water level monitors are susceptible to failure due to battery acid and the harsh environments that are usually associated with batteries. Our water level sensor is a mechanical float made of polypropylene which is not affected by battery acid.
Valves in single point watering systems can fail. You simply cannot rely on gadgetry when the life of your batteries is at stake.
Fast, accurate visual inspection of a mechanical water level gauge is the only foolproof way of knowing when you need to add water to your battery.
How it works:
To indicate when the battery water level is full, the float raises the indicator mark to the “MAX” water level line (see Fig. 1). As the water inside the battery evaporates, the float lowers the indicator mark in the sight glass. As long as the indicator mark is within the green area (see Fig. 1), you do not need to add water.
When the indicator mark is in the yellow area (see Fig. 1), this indicates you should add distilled water to the battery. If the level indicator mark is in the red area, there is still some water left inside the battery, but the battery should be watered immediately since low water levels can damage the battery.
If the level indicator mark falls below the “MIN” line (see Fig. 1), eventually the plates in the battery will dry out and permanent damage to the battery will occur.
When filling a battery, always use distilled water. Never add sulfuric acid to a battery. Normally a battery loses only water since sulfuric acid does not evaporate.
