Identify Two Pressure Switches Logic
Two pressure switches are plumbed together so as to receive the exact same pressure at all times, and they both sense the pressure of compressed air in a pneumatic system.…
McLeod Gauge Working Principle
Measurement of vacuum by two methods : 1. Direct measurement Resulting in a displacement caused by the action of force 2. Indirect measurement or inferential methods Pressure is determined through…
What is a Electric Motor Actuator ?
Electric motor actuator vary widely in their design and applications. Some electric motor actuators are designed to operate in only two positions (fully open or fully closed). Other electric motors can…
Pneumatic Cylinder Air Flow Calculation
This is critical to ensure that the pneumatic cylinder is supplied with enough air flow to operate as it is intended in your system design. This calculation does depend on the type…
Air Consumption Calculation for ON/OFF Valves
Air Consumption Calculation for ON/OFF Valves Generally we specify air consumption in SCFM ( standard cubic feet per minute) for on/off valve as an intermediate (Non-continuous) service. Air Consumption calculation…
Pressure Gauge Installation at Pump Discharge
Remember everyone! Pressure gauge shall be installed after pump discharge nozzle and before check valve. The consequence is if you have two pumps (one is running and another is stand…
TDR & FMCW Radar Level Transmitters Principle
TDR & FMCW Radar Level Transmitters Principle Continuous level measurement via radar is based on the theory of the propagation of electromagnetic waves, put forth by the British physicist James…
Electromagnetic and Conductive limit switches Principle
Electromagnetic Limit Switch The electromagnetic wave measuring process allows for universal use even when the media changes. The electromagnetic wave penetrates the medium and, depending on the respective relative permittivity,…
Basics of Flow Measurement
Flow is defined as fluid in motion. Factors Affecting Flow Rates in pipes are velocity, viscosity, and density of the fluid. Study Basics of Flow Measurement.
Important Factors in Flow Measurement
Important Factors in Flow Measurement are viscosity, density, specific gravity, compressibility, head loss, discharge coefficient, and beta ratio.
