PRODUCT SPECIFICATION — Wet Sieve Analysis Kit

Model: IM-WSA-SSH1 Compliance / target standard: ASTM E11 / Particle Size

The wet sieve analysis kit determines the sand content of a drilling fluid, defined as the volume percentage of particles retained on a 200-mesh screen. It consists of a 200-mesh sieve, a funnel that fits the sieve, and a glass measuring tube marked in percent by volume, together with a wash bottle. Sand content is an indicator of abrasive solids that can wear pumps and downhole tools.

Intended applications

• Measuring the volume percent of sand (particles above about 75 micron) in water-based and oil-based muds.
• Checking the performance of shale shakers, desanders and desilters.
• Detecting drilled solids build-up in the circulating system.
• Wet sieve checks of powdered materials in the laboratory.

FEATURES

• No. 200 sieve, 63.5 mm (2.5 in) diameter, stainless mesh in a plastic or metal frame.
• Glass measuring tube graduated 0-20 % (typical) with ‘mud’ and ‘water’ fill marks.
• Funnel sized to fit both sieve and tube.
• Wash bottle for controlled rinsing.
• Compact kit suitable for rig-site use.

TECHNICAL SPECIFICATIONS

Sieve Designation	No. 200 (75 micron nominal per ASTM E11; often quoted as 74 micron)
Sieve Diameter	63.5 mm (2.5 in)
Measuring Tube Range	0-20 % by volume (typical)
Sample Volume	Mud to the 'mud' mark, then water to the second mark
Reported Result	Sand content, % by volume
Wash Liquid	Water (water-based mud) or base oil (oil-based mud)
Materials	Stainless mesh; borosilicate / plastic tube

Values are typical for this equipment class based on API/ASTM practice and manufacturer literature (OFITE, Fann, Chandler); confirm against the Inmotion datasheet before use in a certificate or specification.

Principle of operation

A measured volume of mud is diluted and poured onto the 200-mesh sieve. Fine solids and liquid pass through while sand-size particles are retained. The retained solids are washed into the graduated tube and allowed to settle, and the settled volume is read directly as a percentage of the original mud volume. The method is a simple wet-sieving separation based on particle size.

Basic operating procedure

1. Fill the glass tube with mud to the ‘mud to here’ mark.
2. Add water (or base oil for oil mud) to the next mark, close the tube and shake vigorously.
3. Pour the mixture onto the clean, wetted 200-mesh sieve; discard the liquid passing through.
4. Add more water to the tube, shake and pour again until the tube is clean.
5. Wash the retained solids thoroughly with a gentle stream until the water runs clear.
6. Fit the funnel upside down over the sieve, invert onto the tube, wash the sand into the tube, let it settle and
read the percentage.

Calibration and maintenance

• Inspect the mesh for tears and blocked openings; clean with a soft brush, never with a needle.
• Check sieve aperture periodically against a calibrated test sieve.
• Rinse all parts and dry after use.
• Replace cracked or scratched glass tubes.

Safety precautions

• Handle glassware carefully to avoid breakage.
• Use gloves when testing oil-based fluids; dispose of base oil correctly.
• Avoid inhaling dust when drying and handling powdered samples.
