4-20 mA signal is preferred over 0-20 mA signal due to its ability to detect faults and provide a clear zero point.
4-20 mA signal has a clear zero point, making it easier to detect faults in the system.
It allows for a wider range of measurement values, as the 0-4 mA range can be used to indicate faults or out-of-range conditions.
4-20 mA signal is less susceptible to noise and interference compared to 0-20 mA signal.

An orifice tab is used to accurately measure the flow rate of a fluid through a pipeline.
It creates a differential pressure across the orifice plate, which is proportional to the flow rate.
The tab is placed upstream of the orifice plate to ensure accurate measurement.
The tab can be designed in different shapes and sizes depending on the application.
It is commonly used in industries such as oil and gas, chemical, and wa...
An orifice in a pipeline can be identified by measuring the pressure drop across it.
Measure the pressure drop across the pipeline using a differential pressure transmitter
Compare the pressure drop with the expected value for the given orifice size
Use a flow meter to confirm the flow rate through the orifice
Inspect the pipeline for any markings or labels indicating the presence of an orifice
Orifice tap is provided to measure the pressure drop across the orifice plate.
Measures pressure drop
Helps calculate flow rate
Used in flow measurement systems
Orifice tab is provided to indicate the size of the orifice and its flow rate.
Orifice tab helps in identifying the size of the orifice and its flow rate.
It is used in flow measurement devices like orifice plates, venturi meters, etc.
The tab is usually made of stainless steel and is welded to the orifice plate.
The tab is marked with a number or letter to indicate the size of the orifice.
The flow rate can be calculated u...
RTD measures temperature using resistance while thermistor uses resistance-temperature relationship.
RTD has a linear resistance-temperature relationship while thermistor has a non-linear one.
RTD has a higher accuracy and stability compared to thermistor.
RTD is more expensive than thermistor.
RTD is commonly used in industrial applications while thermistor is used in consumer electronics.
Examples of RTD include platinum,...
