![]() ![]() Lasers work in a very similar way to radar, but instead of using electromagnetic waves, they use narrow beams of light. We have produced a dedicated post about radar silo level measurement here. One drawback of radar measurement, however, is that it can only measure one spot in the silo and must be angled correctly to give an accurate reading. This gives a measure of the level of the product in the silo, and therefore the volume remaining. The electromagnetic waves bounce back to the radar device in the same way a sound echo is created and the device times how long this takes. Radar devices fitted within the silo send out signals in short pulses and these reflect off the product inside. Radar measurement works with the use of electromagnetic waves. From this, the weight and therefore the volume of remaining product can be calculated.įor more information on weight-based level measurement, see our post What Does a Strain Gauge Do? Radar The load cells measure the weight of the material in the silo, the strain gauges measure tiny movements in the legs brought about by the strain placed on them by the silo and its contents. It is also cost effective and more accurate than manual methods.Īlso called gravimetric level measurement, it involves fitting load cells underneath a silo or attaching strain gauges to the metal legs of the silo. Weighing the contents of a silo is one of the most popular and most accurate ways of determining the volume of product that remains inside. The weight is lowered down to the surface of the material inside the silo and the distance is used to calculate the amount of product left inside. This consists of a pulley system attached to the inside roof of the silo with a weight on a cable. Some silos have windows which enable operators to look inside them, but this can give a false reading if the product is banked up the walls of the silo.Ī more sophisticated form of manual measurement is the weight and cable or yo-yo bin level sensor. It is also the least accurate way to measure a silo. Silo Measuring methods ManualĪt its most basic, manual silo measurement includes climbing a ladder to look over the top of the silo to see how much product remains.Īs you can imagine, this poses a number of health and safety issues. The exact method chosen depends on a range of different factors. ![]() This can be done manually or by radar, laser, ultrasonic, or weight. For effective silo management, it’s essential to be able to measure the amount of material in a silo. Silos are used to store a range of different products. ![]()
