Storage tanks are often placed in clusters or tank farms. The tanks are atmospheric, pressurized or cryogenic. Tank gauging is needed wherever liquids are stored in large tanks at any level of the process

any type of liquid movement and operations depend on reliable and readily available tank information. A loss of tank gauging data will seriously interrupt time-critical operations and product transfers which may lead to unplanned shutdowns.
Our Approach is to Implement a wireless solution to capture a real-time level monitoring system to be customized to any business facility available in the terminal

Storage tanks are often placed in clusters or tank farms. The tanks are atmospheric, pressurized or cryogenic. Atmospheric tanks are vertical cylinders with various roof designs. realtime data centralization is must.

Our Design & Development Process

To meet the high-performance requirements of custody transfer accuracy in tank gauging applications, radar devices typically use the Frequency Modulated Continuous Wave (FMCW) signal processing method. The FMCW method sometimes goes under the name “Synthesized Pulse”.
FMCW is capable of delivering an instrument-level gauging accuracy of better than a millimeter over a 50+ meter range. FMCW is required to make a radar tank gauge accurate, but this is not enough on its own. Precision radar gauges must also have specially designed microwave antennas to be able to deliver both the instrument accuracy and installed accuracy required by custody transfer standards.

There are three main types of applications for radar tank gauges

 Fixed roof tank installation

Floating roof tank installation on a still pipe

Installation on tanks with liquefied gases, pressurized or cryogenic

Strategy & Scope.

This oil level sensor will be installed on one of the oil tank selected from the list provided to us to measure the oil level real-time and display on a dashboard. Data will be transmitted through a wireless network.

Development

A radar tank gauge should be able to deliver the highest accuracy when mounted on existing tank openings. On a fixed roof tank, the openings suitable for tank gauging are normally found on the roof close to the tank wall

Components

The product proposed for this POC implementation is a 26GHz Radar level sensor but for the floating roof type with an 8-inch pipe 80GHz Radar level sensor is selected.
In this model of the sensor, very short microwave pulses with very low emission energy are transmitted and received through antenna systems. Radar waves travel at the speed of light. The running time can be converted into a level signal via electronic components. A special time extension method ensures stable and accurate measurements in a very short time.

Installation

  • Recommended distance (1) from the wall to the outer wall of the installed short pipe
  •  The minimum distance from the pipe wall to the tank is 1/6 of the diameter of the tank, Min 200mm.
  • Cannot be installed above the feed inlet (4).
  • It cannot be installed in the center (3). If it is installed in the center, multiple false echoes will be generated, and interference echoes will lead to signal loss.
  • If the distance between the meter and the tank wall cannot be reach min distance the media on the tank wall will adhere to cause false echoes. False echoes should be stored when debugging the sensor.

Components

Radar Oil Level Sensor (26GHz Radar level sensor)

Junction Boxes

Power supply

Insulated wiring housing

Data acquisition unit

RS485 Cabling

Data Transmitter

Remote Data Display Dashboard

4 or 5G Router

Battery Backup

Prerequisites

1. Power Availability
2. Enclosure for DAU (Data Acquisition Unit), Power Supply, 4/5G Router, Junction Box
3. Junction boxes Mount at the Ground level and near to the Sensor
4. 4/5G Signal available from service provider readily available geographically to plant

This unit is the 24G sensor with 8 Degree beam. Which will mounted
on the manhole or any possible option available at the tank with 200mm distance from the wall of the tank.
DAU and Transmitter

This unit either can be installed with the sensor or the enclosure down at the floor near the tank.
It can be a combination of transmitter and DAU or Router and DAU.
For the POC we will be installing DAU and the 4 / 5G Router.

Measuring Method
This method is implemented in the DAU which will operate from 24V DC current

Flat Roof Installation

We prefer to install on the flat roof tank with a mounting space.

The antenna can be positioned anywhere on the tank roof, except in the center when the tank has a dome roof. For optimum accuracy, a minimum distance from the tank shell is recommended.

Installation Plan

Customer Or By ESS

 

• Install or provide a galvanize casing to DC AWG 20 wires to go from the ground-mounted DAU/Power Supply and the 4/5G Router.
• Mount the Radar Level monitoring Sensor.
• Mount a Junction Box Close to the Sensor (Within 1-2 M)
• Mount an Enclosure provided by the ESS to Install DAU and the 4/5G Router at Ground Level
• Mount a Junction box at ground level and provide 240V AC

Install the ground level Circuit Breaker for the 240v AC power line

Install the ground level Circuit Breaker for the 240v AC power line

Install the power supply (240AC-24VDC) on the enclosure

Wire the Sensor, DAU, Router

Configure the DAU / Router / Sensor
