In this blog we will talk about everything you should know about X flow computer.

What Is the Different Usage of Flow Computer?

To fulfil the intended function, a flow computer should be highly precise and be able to monitor the record measurement in extremely small increment. Another great capacity is the its durability. The devices are in use across various industries especially where it is important to measure and record the remains reliable and accurate. Well, it is crucial to ascertain – the flow computer’s casing and components are designed to perform in a suitable environment you need.

Nowadays, flow computers are used in various industries to obtain precise measurement and analyses products. In some sectors these devices are referred as cash register for being widely used to monitor custody and transfer substances like natural gas and oil. These computers are used to monitor and record steam, liquid and gases by food and drink manufacturers and process metals and minerals in chemical factories, pulp and paper.

Precise Function

Flow computers are used for monitoring the glow of gases and liquid in various types of industries to manufacture food. To obtain optimal result it is best to choose computer that is suited for the purposes.

Nowadays, there are various types of computers available with wide range of attributes and options. It is crucial to select the one that performs with full range of measurements without being cluttered with unnecessary functions.

Apart from the basic function of flow computer that is chemical analysis and gas density calculation, it also performs:

  • Environment compliance monitoring
  • Remote metering
  • Heat flow equation

Most flow computer require some additional configuration and calibration to perform it most accurately. You should also look for models that are easy and intuitive for setting up.

At this situation an overly complicated system can cause setup errors and ultimately cause inaccurate reporting from computers.

Maintenance and Inspection

In order to remail at the peak of function – the computers need to be inspected regularly. It is a good way to assure you are getting precise measurement along with comprehensive records. If the flow computers are installed many years ago and the components may be obsolete and no longer available in market.

With new advances in digital technology computer manufacturers can offer ever-changing precision in measurement. Flow computer is essential for various industry types. Manufacturer relies on it for accurate measurement and analysis of work products. You should maintain it with good order and regular inspection and update them when necessary.

Basics of Electronic Flow Computer

The overall function of electronic flow computer is to calculate the record flow rate using industry standards and other hydrocarbons pass through a meter of segmented section of pipeline. The meters should not be limited to orifice meters, linear meters, ultrasonic meter and Coriolis meter.

For typical measurement application, it needs a differential pressure transmitter, static pressure and temperature probe. Many flow computer uses a multivariable transmitter that can measure differential pressure and static pressure in one transmitter.

For turbine meter, rotary meter and diaphragm meter application a static pressure transducer, temperature probe and pulse generating equipment is required. For other flow meter like ultrasonic meter – the flow computer may use pulse signals from the respective meter, pressure sensor and temperature sensor for computing corrected volume.

What Are the Basic Components?

An electronic flow computer consists of the following components:

  • Enclosure
  • Processor board
  • Display
  • Keypad
  • Pressure transducer
  • Multivariable transmitter
  • Local communication port
  • Power supply
  • Mechanical index
  • Remote communication options
  • Temperature probe

Well, these components are basic of Spirit Flow-X High Accuracy Flow Computers, each application needs its own combination of the basic components.

Remote Communication

There are various options available for remote communication with electronic flow computers.

It includes:

  • Dialup phone line
  • Wiriness radio
  • Satellite
  • Cellular
  • Ethernet

For every options an appropriate modem or interface board is required to be connected to the PCBA. In addition, for each communication type, the proper baud rate and any related communication parameters should be setup in the flow computer.

The electronic flow computer is identified in field by the unique Site Identification address. It is particularly important to identify the flow computer while communicating.

Wrapping up

Electronic flow computer is just one piece of the EGM system. The flow computer collects live uncorrected gas and liquid volume through any type of meter and calculates the corrected volume and energy.

It is particularly achieved by measuring live differential pressure, live flowing pressure, live flowing temperature and by counting pulses from meter.

In addition, other devices can feed the flow computer like online chromatophore to offer additional data that allows more granular look at volume and energy.

Accurate Liquid Turbine Flow Meters for Oil and Gas Applications

Image
Chemical blending, custody transfer, and petroleum processing are just a few of the applications where precise liquid flow measurement is essential. To guarantee accurate and trustworthy measurements, high-accuracy liquid turbine flow meters are needed. Since it is so accurate and dependable, the liquid turbine meter has become very popular. This blog will go into greater detail about the Daniel 1500 Turbine meter . Knowing How Turbine Meters Work The purpose of a turbine meter is to gauge the volumetric flow rate of liquids moving through a pipeline. The force of the flowing liquid rotates a turbine rotor that is placed inside the flow stream. The electrical pickoffs on the meter body then transform the rotating speed of the liquid as it passes through the turbine meter into electrical signals. Accurate measurement is possible because the electrical frequency output is proportionate to the flow rate, with each pulse denoting a tiny incremental volume of flow. Turbine Meter C...
