Linear Chemical Feed with Walchem's E-Series Pumps

One of the big disadvantages of solenoid driven metering pumps is their pulsation leading to slug feeding of chemicals into the process. Despite their advantageous cost, this surging of chemicals can cause havoc with sensors trying to monitor the process.

Differential Pressure Sensors | Hydroelectric Power Generation

Submitted by Ravi Jethra || Wika

In hydroelectric power generation, dirt and debris in the intake water can shorten the lifetime of turbine blades. Filters inside intake pipes trap the debris so that only sediment-free water hits the blades. A differential pressure sensor/transducer measures the flow. Learn more.

Reduce the Risks of Particulate Contamination, Seized and Galled Threads with Gall Resistant Fitting on UHP Pressure Gauge

Submitted by Don Eisenhart || Wika

Replacing standard alloy fittings on a pressure gauge with gall resistant fittings is a minor change, but doing so eliminates the major issues associated with standard fittings. Fittings in a gall resistant material ensure a leak-tight seal, prevent particulate contamination from silver flaking, and minimize damage to the equipment caused by cross-threaded and/or seized fittings.

Power Plant Turbines: Temperature, Pressure & Flow Measurement

Submitted by Ravi Jethra || Wika

Flow measurement, along with measuring temperature and pressure, are critical for optimal operation in gas and steam turbines. If these parameters do not stay within appropriate ranges, a power plant will suffer from issues with safety, performance, and efficiency. Learn more.

Pressure Transmitter Accuracy & Non-Linearity: Not the Same

Submitted by Robert Lukat || Wika

Sometimes, references to pressure transmitter accuracy are actually about the non-linearity of the pressure transmitter's response. Although accuracy and non-linearity are related, the two terms are not the same and shouldn't be used interchangeably.

Improving Industrial Gauge Readability | Safer Operations

Submitted by Hardy Orzikowski || Wika

Pressure and temperature instrument dials with big, bright numbers increase instrument visibility and readability. WIKA USA's retro-reflective dial background makes it even easier to locate a critical installation among the sea of industrial gauges, adding to the speed of taking a correct reading.
