Multivariable Transmitter

Multivariable Transmitter

The multivariable transmitters are devices specifically designed to measure three process variables at a time. These types of transmitters are used for pressure, differential pressure, and temperature measurement along with the flow rate of process line fluids.  All industrial operations are mostly dependent on different process variables which need regular monitoring and control. Generally, industries used for accurate mass flow measurement require three transmitters Pressure, Differential pressure, and Temperature transmitter resulting required high materials, installation, and maintenance costs associated with multiple process connection and wiring connections. That's the reason innovators invented a single device which is known as a multivariable transmitter. It is accessible to three process measurement and flow calculation.

Working Principle of  Multivariable Transmitters

We have some points that help us understand the overall working of a Multivariable transmitter.

• The Multivariable Transmitters feature three sensors in a single design. It consists of a static pressure sensor, a differential pressure sensor, and a temperature sensor integrated into a capsule sensor design.
• The Electronics units are set with a coded formula, which gives a calculated value of the mass flow reading.   
• The Multivariable transmitter is based on the HART protocol that helps in monitoring, control, and calculations in a time-lapse cycle.

Advantage

1. Easy to install.
2. Reduce the high maintenance cost.
3. Highly accurate for measurement of the flow of gases, vapors, and liquids in industrial applications.
4. It reduces pipe penetrations, thus saving impulse piping, and connection systems with measurements in a single device.

FAQ

What is a multivariable transmitter?

It is specifically designed to measure three process parameters and calculate the flow during an active industrial operation. These types of instruments offer static pressure, differential pressure, and temperature measurement along with a flow calculator.

How does a multivariable transmitter work?

The Multivariable transmitter measures and calculates the mass flow as a function of differential pressure as well as absolute pressure and temperature. Therefore it should be used whenever differential pressure flow measurement needs a compensation of temperature and pressure.

What is a multivariable flow meter?

Multivariable flowmeters are capable of providing additional process measurements and process information, including process temperature, line pressure, fluid properties, and specifics about the pipe geometry.
