There area a number, however various versions of them rely on measuring the level in the silo, in a fashion similar to what you have already done with a tape measure (and the tape will be more accurate – no electronic gizmos to drift out of the range or be smashed off etc).

How about:

Radar, microwave, ultrasonics (maybe – depends on the dust), capacitance, level switches at known incriments etc

Or maybe

Load cells, strain gauges, maybe thermography etc

Empty silo and then measure material influx

Etc

tq

i check of ultrasonic but they have limitation with the range and some not able to work under dusty environment eg cement silo and clinker silo.

we have at this moment silo pilot but i only can rely silo pilot on top of cement silo but for clinker silo uncertain on the reading not accurate.

any sharing pls ■

The Q is a bit cryptic to me, at least, however maybe this is the straight vertical height of the silo + the vertical height of the hopper to find the total load at the bottom of the silo.

hi to all

one of sale agent promoting siement product recommended to use radar measuring device for clinker silo heigh measurement and he ensured the device work properly in the dusty environment ........the product is among the latest technology available..........

but i just want to survey anybody use siemen radar measuring device..........how good and reliable the device.......pls advice..........

tq ■

i want to know about device performance..... ■
