Conductivity vs. Fluorescence for Sugar Leak Detection in Boiler Condensate
Sugar mills have relied on hourly manual condensate sampling for decades, precisely because a sugar leak into boiler condensate is expensive and dangerous to leave undetected. The problem is that manual sampling and conductivity-based online monitoring share the same underlying weakness: neither one is sensitive enough to catch a leak while it’s still small, so […]
Condition-Based vs Outcome-Based Cooling Tower Water Treatment: Measuring the Result Instead of the Recipe
A cooling tower can run within every setpoint on the controller — conductivity in range, pH in range, ORP in range — and still be forming scale, growing biofilm, and corroding the heat exchanger. That’s not a contradiction. Conductivity, pH, and ORP were never measuring those failures directly. They were measuring conditions that make those […]
Corrosion Coupons vs. Corrosion Rate Sensors: Why Waiting 90 Days to Find Out Is a Problem
Most cooling tower and chiller operators find out about a corrosion problem in one of two ways: a coupon comes back from the lab with a number that’s already 60 or 90 days old, or a leak develops and the corrosion has already been happening for months. Both are after-the-fact. Neither tells you what was […]
Smart Paddy Farming: How IoT Sensors Are Closing Malaysia’s Data Gap
Most paddy fields in Malaysia are still managed the same way they were a generation ago: irrigate on a fixed schedule, apply fertiliser by habit, and check for pests by walking the bunds. It works, until it doesn’t. By the time a farmer spots a stressed patch of paddy or a moth population that’s gotten […]
Why We Stopped Selling Smart Irrigation Until the Hydraulics Were Right
In August 2020, we commissioned our first smart farming project on a 5-acre farm in Melaka, managed by an experienced farmer who had been working the land for years. The farm was divided into blocks, each taking turns to be watered and fertilised through a centralised fertigation system with four outputs, each controlled by a […]
Why EC Is the Wrong Way to Manage Fertigation (And What to Use Instead)
Electrical conductivity — EC — has become the default parameter for managing nutrient dosing in commercial horticulture. Growers target an EC setpoint, their controller doses fertiliser until EC reaches that number, and they call it done. The problem is that EC does not tell you how much nutrient a plant received. It tells you how […]
What Happens When You Run a Boiler Monitoring System Without a Sample Cooler
Every boiler feedwater and steam condensate analyser on the market — including the Pyxis Guardian IK-2000 series — specifies that it must be installed downstream of a sample cooler. This requirement is stated prominently in the installation documentation, with operating temperature limits of 40–49°C at the sensor inlet. In practice, sample coolers are frequently omitted […]
Why Cation Conductivity Tells You More Than Standard Conductivity in a Boiler System
Standard conductivity measurement is one of the most common parameters in boiler feedwater and steam condensate monitoring. It is fast, inexpensive, and gives a useful general indication of total dissolved solids. But in power generation and co-generation applications, standard conductivity has a significant limitation: it cannot reliably distinguish between contaminants that are genuinely corrosive and […]
The Consequences of Running a Cooling Tower Above Its Maximum Cycles of Concentration
Cycles of concentration is one of the most important parameters in cooling tower operation. It determines how much mineral content builds up in the circulating water relative to the makeup water, and it directly controls both water consumption and the risk of scale and corrosion. Most operators know they should monitor it. Far fewer understand […]
Why Conductivity Alone Is Not Enough to Control a Cooling Tower
Conductivity control is the foundation of every cooling tower water treatment programme. It keeps dissolved solids from concentrating to the point of scale formation, and it triggers the bleed-and-dose cycle that maintains chemical treatment levels. It is necessary. It is also not sufficient. A cooling tower controlled only by conductivity is a system that manages […]
