Better Than an Orifice Plate: WIKA’s FlowPak Flow Meter Offers Versatility, Efficiency, and Savings
| Nicholas Steele | FlowThe orifice plate and other devices for differential pressure (DP) flow measurement have both positive and negative attributes. WIKA’s innovative FlowPak features all the benefits of traditional DP flow meters but with greater accuracy and less drop in pressure. …
Grain Growth in Type K Thermocouples: Some Causes and Solutions
| Robert Torgerson | TemperatureExtremely high temperatures over time lead to grain growth in type K thermocouples, which can cause metal separation and thermocouple failure. Fortunately, good solutions exist for minimizing the effect of grain growth. Grain growth is a common cause of failure in …
How Green Rot Affects Type K Thermocouples
| Adam DeLancey | TemperatureGreen rot is most pronounced when type K thermocouples are exposed to temperatures between approximately 800°C and 1,260°C (1,472°F to 2,300°F) and when there’s a low concentration of oxygen. This problem causes negative drifts, inaccurate measurements, and even …
Float-Based Level Measurement Is Ideal for Pharma Fermenters: A Case Study
| Michael Muth | LevelInstrumentation that uses a float to measure level and transmit signals can be optimally adapted to challenging media conditions. WIKA’s level measurement engineers helped a major pharmaceutical company find a replacement for its older level sensors that were not as …
