The equipment a farmer owns is very important as it helps him to run his establishment more efficiently. Farms that specialize in grains have storage silos, or elevators, of various sizes. In older times, these silos were constructed from wood, but more recently they have been made of concrete or corrugated steel. These silos can be huge, depending on the size of the farm, and therefore farmers use grain level indicators to help them determine how much produce they have stored.

As of late, farms and communities in the same area have also started using one nearby storage facility, and these constitute huge silos. New inventions have enabled farms to operate more efficiently, and to help avoid potential problems, such as explosions caused by the dust of grains. The gauges that have been invented have also solved the problem of silos overflowing with grains.

There are different gauges that are used for different purposes. One type of gauge is used to determine only when no more produce should be added to a silo. This is the most common type used. Other gauges are a bit more fancy, and measure the current level of grains in the elevators. These can be useful for many reasons as well.

A tilt switch indicator is an example of a type of gauge that farmers use to prevent the overfilling of their storage facilities, and there are several ways in which these switches operate. One has a steel ball that turns on an electric switch, while another is based on a mercury concept. Others with no mercury are also available. Farmers should consider the positive and negative aspects of each type of tilt switch before they decide which one to purchase.

The cheapest of the above-mentioned is the mechanical switch, and its main advantage is that it does not work with mercury. It does have several parts that are in constant motion, however, and it cannot be used in areas where explosions are a problem. Mercury is a harmful substance, and this is naturally a disadvantage of the mercury switch, but it can be remotely operated, with is one of its advantages.

The solidstate switch contains no mercury, but is the most expensive design. It is also only driven by remote control, and cannot be directly connected to the control system. The type of tilt switch indicator a farmer chooses to buy may depend on the price he can afford, or upon the environment in which it will be placed.

The second type of gauge available is the rotary paddle bin indicator. It consists of a motor which turns a paddle above the produce. When the silo is busy filling up it turns freely, but when the silo is full, the motor will switch off. The farmer will then be warned that the silo is full.

Elevators of grains can be put to work much more efficiently if they are installed with grain level indicators. Although the equipment will cost a bit of money, the farmer will find it a necessary expense. Farmers may also wish to consider purchasing the gauges that measure inventory levels.
