Absolute Humidity vs Relative Humidity

Leave a Comment

Moisture analysis involves the process of measuring moisture and humidity in a particular environment. In general, humidity refers to the amount of moisture in the air; however, humidity can be measured in two ways: absolute and relative. Absolute humidity and relative humidity measurements are crucial in a wide range of applications from HVAC and drying […]

Moisture Analyzers for Emission Monitoring

Leave a Comment

As we become more aware of the environmental impact of industrial operations, governments and regulatory organizations around the world continue to establish increasingly stringent emissions requirements. In order to ensure compliance with the latest emissions standards, most industrial facilities employ emissions monitoring systems with moisture analyzers to observe and modify pollutant concentration in their emissions. […]

What is Stack Emission Monitoring?

Leave a Comment

Stack emission monitoring is a process that enables facility managers, inspectors, and other key personnel to measure the level of industrial waste and/or pollutants a stack emits into the atmosphere. Monitoring emissions from stack facilities air quality monitoring and measures the efficacy of pollution control equipment. The data gathered may also be used to prove […]

Applications of the MAC STM and STMT Steam Flow Meters and Transmitters

Leave a Comment

Steam flow rate is typically measured using orifice plates, nozzles, venturies, or vortex sheading flow meters. All of these devices respond to volumetric flow, not true mass flow. For any fixed volumetric flow, the mass flow will vary with the line pressure. If the absolute pressure is doubled, the density of the steam will double […]

What’s Wrong with Relative Humidity Above 100°C?

Leave a Comment

Water vapor above a temperature of 100°C at atmospheric pressure is in the super heated state. The characteristics of the relative humidity scale change drastically in the super heat area. It is somewhat like going through the sound barrier, the physics take on new characteristics in the super heat area just as they do in […]
