Frequently Asked Questions (FAQs)
What is a Differential Pressure Transmitter?
A differential pressure transmitter measures the difference in pressure between two points and converts it into an electrical signal. It is commonly used to measure liquid level, flow rate, or pressure drop in industrial systems.
How does the Differential Pressure Transmitter work?
It measures the pressure difference between the high-pressure and low-pressure sides of a tank or pipe. The resulting pressure differential corresponds to the liquid height or flow velocity and is converted into an electronic output signal.
What is the operating principle of this transmitter?
The device works on Faraday’s Law of Electromagnetic Induction, where a voltage is induced in a conductive fluid moving through a magnetic field. This voltage, proportional to the flow velocity, is amplified and processed to calculate the flow or level value.

In which industries can it be used?
It is ideal for chemical, pharmaceutical, water & wastewater, oil & gas, power, and food & beverage industries — wherever accurate differential pressure or level monitoring is required.
What are the typical output options available?
Standard output is 4–20 mA, with optional RS-485 (Modbus RTU) communication for digital control and remote monitoring.
How is the transmitter installed and maintained?
The device is installed by connecting the high- and low-pressure ports to appropriate process points. Routine calibration and keeping the ports free from blockages ensure long-term reliable operation.
