The ZNH-1Instrument for measuring sand content in mud
1. Summary
This is a simple and reliable apparatus for measuring sand content of drilling fluids effectively and accurately. The method that screen decomposes is used to decide the content of sand. The sand content of drilling fluids is defined as the percent ratio of the volume of sand which can not pass through the screen mesh No. 200, i.e., whose diameter is larger than 0.074 mm, to the volume of the drilling fluid.
2. Model and specification
Model: ZNH-1
3. The main technical parameters of apparatus
The major technical parameters of the instrument are listed in the following table.
