• Patented Design (US 20130080074 A1).
It is possible to automate any type of
Infiltrometer and Permeameter by weighing the
water reservoir instead of manually reading
water level change in it. Then I designed an
automated Double-Ring Infiltrometer, an
automated Pressure Infiltrometer and an
automated Tension Infiltrometer. Soilmoisture
Equipment Corp. (SEC) then applied for a more
inclusive patent for the idea which was
approved on 2014.
• Aardvark Permeameter (Model 2840)
Aardvark Permeameter is the first automated
permeameter in the world. It was also my first R&D
project in SEC. I was the head of Aardvark project. My
contributions were in the areas of technical, scientific
and market research, designing, manufacturing,
performance evaluation, quality control, instructional
and promotional documents, videos, sales efforts,
demonstrations and training sessions, sales and
customer support.
• Aardvark Permeameter Operating Instructions
Aardvark Permeameter operating instruction was the first operating instruction I created for SEC.

• Aardvark Elemental (Model 2800BE2)
I designed Aardvark Elemental as an affordable version of manual
Aardvark Permeameter. It is a great option for educational purposes and
where price is a critical factor. Aardvark Elemental is not automated, yet it
still has several advantages over other “regular” permeameters.
• Aardvark Permeameter Software Application Operating Instructions.
Right after finishing and debugging Aardvark Software Application, I created a comprehensive Operating
Instructions for it.
• Guelph Permeameter (revised edition) (Model 2800K1) Operating Instructions.
Since Guelph Permeameter Operating Instructions was outdated, I revised it in 2012. Fortunately
professor Elrick and Dr. Radcliff (the inventors of Guelph permeameter) were very pleased with the
outcome.
• San Andreas Soil Particle Analysis System (Model 0318K1)
It is a complete soil particle analysis kit. It is also
battery powered and thus portable. The system
provides the means for “Sieve Test” used for
determining sand content and “Hydrometer
Test” for determining the percentage of silt and
clay.
• San Andreas Soil Particle Analysis System (Model 0318K1) Operating Instructions.
It is actually two Operating Instructions in one document. Soil Texture Determination Instructions is a 2-
hour test for determining soil texture in the field; while Soil Particle Analysis method is a 24-hour
procedure for creating Soil Particle Distribution Curve. Both procedures are described in a stepwise and
easy to understand manner accompanied with several descriptive pictures.

• Tempe Cell System (Model LAB-5 and Model LAB-6)
Tempe Cells are miniature pressure extractors
usually used for undisturbed soil cores. I designed
and developed a complete system for SEC Tempe
Cells. I also improved SEC Tempe Cell Stand and
added a built-in manifold to it. This is a great help
when several Tepme Cells are connected to a single
pressure regulating system.
• Tempe Cell System (Model LAB-5 and Model LAB-6) Quick Start Guide.
• Automated Soil Hydraulic Conductivity Measurement System (Laboratory Setup)
The system was made using SEC new products (e.g.
new Tempe Cell Stand, Monitor Transducer and
Monitor Software Application). The system is scalable
up to 20 Soil cores. Readings are stored automatically.
The system is designed for Constant-Head and also
Falling-Head methods. It was inspired by THE UMS
Ksat instrument. My design has several advantages
over the UMS system including convenience, cost,
scalability, flexibility, durability and reliability.
• Automated Soil Hysteresis System (Laboratory Setup)
Hysteresis in soil water retention function is an
interesting and also basic phenomenon in soil
physics.
Conventional Setups are hard to implement and
laborious (manual readings for a long time). Using
SEC new precession pressure sensor (Monitor
Transducer) I designed an automated soil hysteresis
system. It is very easy to setup and readings can be
made manually or automatically.

• Model 1914 Multi-Depth Soil-Water Sampler
Model 1914 sampler was designed as a critical component for Quantifield
System. The standard model consists of 6 individual ceramic samplers on
a single probe. It is designed for chemical profiling and tracing elements
and compounds in soil profile.
• Automated Pressure/Vacuum Pump (Model 2008F1)
Soilmoisture electronic pressure/vacuum pump was not
automated when I arrived in SEC. On the other hand, there
was a pressing need for such instrument since SEC did not
have any other automated vacuum source for vacuum Lab
Setups. I converted SEC electronic pump (Model 2008) to an
automated pressure/vacuum pump (Model 2008F1). This
was accomplished with minimum modification to the
original product.
• Automated Pressure/Vacuum Pump (Model 2008F1) Quick Start Guide.

• Guelph Permeameter Calculator
Guelph Permeameter is one of the most famous and
popular permeameters in the market. However, performing
related calculations has always been a challenge for
consultants, students and even scientists. I created Guelph
Permeameter Calculator to compliment Guelph
permeameter and make life easier for workers in this area.
The calculator is created based on Reynolds and Elrik
solutions and is capable of performing “single-head”,
“double-head” and “average head” methods.
• Silica Sand and Bentonite Clay Calculator
Soilmoisture sells considerable amount of Silica Flour
and Bentinite Clay every year. The main application is for
soil-water sampler installation. It is always hard to guess
how much of these products are needed. I created a
simple calculator that helps users and also SEC sales
agents to calculate the total amount of Silica Flour and
Bentinite Clay needed based on order information.
• Soil Particle Analysis Calculations
The calculator is an MS-Excel version of the computer
application (included in SimplyData Software Suite). It
performs complete “Sieve Set” and “hydrometer”
analysis. The calculator was used as a basis for creating

• Instructional and Promotional Videos:
Creating instructional and promotional videos was my other major contribution to SEC. Instructional videos
are important parts of tech support efforts in today’s market. SEC did not have any YouTube Channel and
instructional videos by the time I arrived. I therefore, started working with a small team and I managed to
create several instructional and promotional videos. Today, SEC has about 30 videos in its YouTube Channel.
Also several videos are in process of edition.

• Calculating Aardvark Permeameter Operational Range:
Aardvark Permeameter is developed in SEC as the first automated borehole permeameter. There was a need
for measuring accuracy level and also operational range of Aardvark Permeameter. A suitable laboratory setup
was designed and several measurements were performed to collect the required data. A mathematical model
was created to calculate Saturated Hydraulic Conductivity (K) based on four methods of calculation and due to
different scenarios. Measurement Error was calculated using Aardvark Scale accuracy and resolution and also
system water loss due to leakage and evaporation.
• Determining Aardvark Permeameter Head Height Repeatability:
Aardvark Permeameter establishes a constant head
height at the bottom of borehole. Variations in the
established head height increases measurement error. A
lab setup was designed and used to make it possible to
measure head height accurately. The results then
analyzed and reported.
• Measuring Soil Moisture Profile Using MiniTrase (TDR technology):
Moisture profiling or as we called it “incremental
reading” was an interesting project with the goal of
using MiniTrase (SEC TDR device) probes to read soil
moisture profile by inserting the probe in soil 10-cm-
at-a-time. Several different probes in different
lengths were used in 6 different levels of dielectric
permeability from 1 (air) to 80 (pure water). Tens of
readings were made and great results were obtained
(in terms of correlation and repeatability). Once
finished, it will be the first practical portable
moisture profiling system ever introduced.
