Hello, the aggregate plant I work at uses a great deal of siemens-milltronics control equipment for silo level indicators. They also use this brand for their belt scales. I recently replaced one of these belt scales with a Beltweigh system, which has worked flawlessly since its installation, whereas the siemens lasted about 3 days. Unfortunately, Beltweigh doesn't deal in level indicators, so I would like to know if anyone can recommend another brand of level indicator to replace the siemens. In addition to their products being unreliable, they offer very poor customer service. Thanks.
