On May 6, a rocket will lift off bound for the International Space Station (ISS). On board will be a liquid flow sensor from Sensirion AG, Stäfa, Switzerland. The sensor is part of a research project by Minnehaha Academy in Minnesota that is investigating the impact of microgravity on the effectiveness of liquid flow. Among […]

Single Unit Controls Bidirectional Mass Flow and Pressure
Alicat Scientific, Inc. designers wanted to replace separate instruments and allow researchers to make rapid changes to experimental setups. Their answer was the MCD-Series bidirectional mass flow and pressure controllers. This single unit delivers precise and rapid control of mass flow rate, volumetric flow rate and absolute pressure of gases in two flow directions. Users […]
Flow Meters Address Several Industrial Applications
Automotive, chemical, oil and gas, pulp and paper, metals, printing and rotating machinery are just a few of the targets for Badger Meter Model IOG flow meters. Designed to measure very viscous (up to 1,000 cP) and caustic fluids, such as oils, coolants, fuels, lubricants, ink, paint, water solutions, and any other liquid compatible with […]
Wireless Sensing for Data Centers
The ever-increasing volume of internet data requires handling many megawatts of power in data centers and dealing with increasing server densities. Maintaining an environment that ensures uninterrupted long life for the servers and minimizes electricity costs dictates the use of complex cooling and environmental monitoring systems. For scalable monitoring, LORD MicroStrain’s wireless sensor network technology […]
Sense Air in Line to Avoid Problems
When fluids flow in tubes for patients, the presence of air in the line creates significant problems. To detect the presence of air, Morgan Technical Ceramics uses its piezo ceramics capability in ultrasonic sensors. The Air in Line (AIL) sensors include a bubble detector for a 4-5 millimeter (mm) tube. Operating at a nominal resonant […]
Scaling Shrinks Flow Sensor
When a design works well and is widely accepted in the marketplace, it makes sense to take advantage of its capabilities but modify the design to meet new requirements. By scaling its thru-FlowT Pressure Transducer technology, DJ Instruments maintained the 100% swept ID surfaces but significantly shrunk the size of a transducer that is used […]
Low-flow Mass Flow Controller
Brian Kinkade, sales development manager for Leister Technologies explains low-flow mass flow controller to Sensor Tips’ Randy Frank at Sensors Expo 2011. With a 1000 to 1 turndown ratio, the units provide a full dynamic range for inert gas control. For more information about Leister Technologies Axetris MFC 2100 series and other mass flow meters […]
MEMS-Based Gas Meter Flow Sensors
Experts predict that gas meters are poised to undergo the same change as electricity meters for smarter, remote meter reading. In response, STMicroelectronics and Omron have collaborated to provide a complete solution for electronic gas meter flow sensors. The design uses an Omron transducer and a companion analog front-end chip developed by ST. The resulting […]
Sensirion Flow Meter Addresses Milliliter Applications
For flow rates below 100 ml/min, Sensirion’s SLQ-HC60 flow meter provides a reliable and inexpensive solution for automated systems and other applications. Using its CMOSens Technology that integrates signal conditioning circuitry and microelectromechanical systems (MEMS) structures in a CMOS microchip, Sensirion’s SLQ-HC60 flow meter provides a 0–10V analog output signal from a supply voltage of […]
Honeywell Zephyr Digital Airflow Sensors Provide 2.5% Accuracy
Using a microelectromechanical system (MEMS) sense die and an Application Specific Integrated Circuit (ASIC) for signal conditioning and interfacing, Honeywell’s Zephyr Digital Airflow Sensors achieve 2.5% accuracy. The fully calibrated and temperature compensated HAF Series are available in standard flow ranges of ±200 SCCM and ±1000 SCCM. The MEMS design has thermally isolated heater and […]
