Melt pumps used in polymer production are a special high temp positive displacement pump used at the discharge of an extruder to assure a smooth, high temperature and high pressure (often several thousand psi) supply of the polymer to the filter screen and die for better throughput and uniformity of product. Blockage of the filter screen or die can cause spikes in pressure high enough that the die can be damaged or blown off the feed tap. When that happens, the released polymer will cool and harden at ambient pressure and temperature, requiring hours of cleanup. Downtime costs can be significant.

Meeting the Challenge of Portable Moisture Measurements
If you’re a user of moisture analyzers, you’ve probably experienced challenges in performing a quick, accurate measurement using a portable instrument. Portable moisture analyzers are typically used to verify the moisture reading of a fixed-installation instrument or to conduct spot-sampling measurements at remote sites which lack a permanently installed device. In my experience performing portable measurements, I’ve seen several common obstacles a user may encounter:

Application Spotlight: Wireless Monitoring of Hydroelectric Dam Levels
APPLICATION:
Hydroelectric dams and their reservoirs store a significant amount of energy, which can be fed into the grid very quickly, when necessary. In determining the amount of available energy, the water level height at the reservoir must be monitored accurately by a reliable monitoring system.

4 Reasons Thermal Mass Flow Meters Make Sense in Pharmaceutical
Excessive gas consumption wastes money - and of greater importance - can affect product quality and safety. The pharmaceutical industry uses large quantities of nitrogen, oxygen, carbon dioxide gas, and air. Without good air and gas flow measurement, cost, quality, and consumer safety will suffer.

Measuring Water Vapor in Hydrocarbon Streams
Extracted from a variety of different sources, natural gas is composed of many different hydrocarbons and includes other, less desirable, impurities. These impurities – such as water, carbon dioxide, and hydrogen sulfide – are removed due to adverse effects, including:
- Reducing the heating value of the natural gas
- Damaging piping and other mechanical hardware due to freezing or corrosion
- Meeting tariff limits associated with transaction contracts

It is safe to say that everyone’s goal in process control is to increase reliability of their process measurements. Facilities spend endless resources to identify and displace problematic points, also know as “bad actors”. One common problem area in a refinery is reliably measuring the heavy residual hydrocarbons from the “bottoms” of the distillation towers in the crude unit. Typically, these applications are Vaccum Distillation (VDU) Feed & Delayed Coker (DCU) Feed; also known as crude furnace pass flows.

Direct Mass Measurement of Flare & Combustor Gas Flow Rates
Providing exceptional low-flow sensitivity for accurate measurement over a wide range of flaring operations
Flare stacks and combustors are used to burn waste gases from the plant, converting chemical and organic hydrocarbons into primarily water vapor and CO2. Some processes also use relief valves to vent flammable gases to the flare stack during upset conditions.
Applications include oil and gas well drilling operations, oil refineries, chemical process plants, gas distribution infrastructure, and landfills. Flares are subject to stringent regulations, requiring operators to measure, record and report the amount of flared gases.
Due to the potential for large changes in flow rates, density, pressure and gas composition, flare gas measurement is one of the most difficult and demanding flow applications. Fox Thermal flow meters have demonstrated their ability to measure the low-flow rates typical of normal flare conditions, and also the high velocities found in upset conditions.
Fluid composition and installation anomalies can also affect flow meter performance. Fox Thermal's calibration lab employs a wide range of gases, gas mixtures, temperatures, pressures and line sizes to simulate actual fluid and process conditions. This real-world approach improves installed accuracy and minimizes measurement uncertainty.

Elevating Success: Measurements in Wastewater Lift Stations
Written By TechStar Solutions Specialist, Josh Longcor
Lift stations are collection facilities designed to move wastewater from lower to higher elevation through pipe systems, particularly where elevation changes are not able to provide gravity flow or where excavation and sewer construction costs are high. These collection stations are automated because there is no regular onsite personnel present to ensure their operation. They use electrical, mechanical and control equipment to ensure reliable operation and require intermittent inspection to ensure they function properly and are not nearing a potential failure.

Do you have Fired Heaters, High Performance Furnaces, Incinerators, Selective Catalytic Reduction Units (SCRs), Flare Lines, Tanks to blanket, Reactors to monitor, Marine Terminals for loading or unloading ships and barges? If so, then you probably either have online gas analyzers or need them. Many people that own these assets really don’t like online process analyzers or don’t like what it take to keep them running. Traditionally these analyzers have been more complex then most of the instrumentation that is used in our industry. This leads to performance less than the user would expect.
