Bitumen Flow Meter

Bitumen flow meters are affected not only by the viscosity of the liquid, but also by its lubricating properties and pressure. Gear damage can be reduced by using a medium with good lubricating properties. Bitumen flow meters are also frequently used in conjunction with automated metering equipment.

One of the shortcomings of bitumen flow meter is that compared with other flow meters, there are limitations in the diameter of the selection. Generally, the range of flange diameter that can be satisfied is about DN10-DN200. Secondly, Bitumen flow meter has strict requirements on liquid medium temperature and liquid pressure. There are many metal parts in the asphalt PD meter, which are thicker and heavier. The minimum appearance that can be customized is limited, so it can be said that the bitumen flow meter is relatively bulky.

What is the problem encountered during the measurement?

Trouble 1:  oval wheels don’t rotate.

1. Solid particles fell into the bitumen flow meter and the gears got stuck; clean the inside of the bitumen flow meter.

2. This machine has been set for too long, causing the internal wheels to rust; you can re-purchase gears of the same specification to replace the original gears.

3. The flow rate is too slow and the pressure of the liquid is too small; confirm whether the water level is full or increase the flow rate of the liquid appropriately.

4. There was an error in the transmission system, and the gears inside the flow meter stopped rotating; test the signal transmission system on the flow meter again to find the problem.

Trouble 2: The hands don't move, but the gears work

1. The magnetic coupling is damaged; find the damaged parts and replace them

2. The counter is damaged; disassemble and check it and replace the damaged parts.
