Product Description - Rapid Moisture Meter
What is Rapid Moisture Meter?
The Rapid Moisture Meter is used to quickly determine the moisture content of materials in powder form, i.e. Earth, sand, coal, ceramic paste, cement, etc. Calcium carbide in contact with moisture from the resulting acetylene gas. This principle is used in a rapid moisture meter.
Rapid Moisture Meter consists of a pressure vessel with clamp to close the lid, capacity. Rubber seal, manometer calibrated in percentage of moisture based on wet weight, scale for weighing the sample, spoon for measuring carbide reagent, reagent bottle, cleaning brush and 4 steel balls for thorough mixing. Complete in polished wooden crate with carrying handle.
Rapid Moisture Meter Method
The rapid moisture meter measurement method is a quick method of determining the water content of a soil sample. This method is carried out using devices called Rapid Moisture Meter. It is a handheld, suitcase-like device that can be easily deployed in the field.
The rapid moisture meter equipment box consists of a scale, a calcium carbide bottle, a spoon, some steel balls and a bottle-like metallic container that has a sealing cap to make it watertight, and this container is equipped with a manometer calibrated to produce gas pressure as a percentage of the amount of water present in the total weight of the soil.
Rapid Moisture Meter Procedure
Firstly we take some 5-6 gm. of soil sample into the pan of balance. After balancing the weight we place the weighed sample into the metallic bottle. Next we insert 3 – 4 steel balls into the bottle and deposit a scoopful of calcium carbide inside the bottle. Clamp the bottle air tight and shake it for 2-3 minutes.
By this vigorous shaking both soil and calcium carbide get mixed completely and the calcium carbide reacts with the free water present in the soil sample and produces acetylene gas.
This produced gas develops pressure into the bottle which gets notified on the gauge meter.
For this reason this test is also called Calcium Carbide Method.
Meter gives the value of percentage of amount water present in the soil sample. That is if we get the value on the meter as 4 % then that means in the soil sample 4 % is water and 96% is solids.
 Let’s say rapid moisture meter reading is wr %.
 So water content being weight of water to the weight of solids will be this.
Water content (w) = weight of water (Ww) / weight of solids (Ws)
w = wr/100-wr
And multiplied by 100 for the percentage value.
That is, from the water content obtained on the wet mass basis as the reading on the rapid moisture meter calculation, the water content on the dry mass basis shall be calculated as follows:
w= [wr / (100-wr)] X 100 %
