Working with the levelmeter and analyzer consists of two stages:

Measurement №1 (calibration) - the results of this measurement are as follows: the value of speed of sound propagation in this liquid, type of liquid and its density at the current temperature.

Measurement №2 - the measurement result are:

The fluid level, the presence of underproduct water, the volume and mass of the analyzed liquid.

For a mixture of propane/butane the ratio of its components, pressure, density and vapor mass are defined additionally.

Measurement time is 3-5 seconds.

To maintain high measurement accuracy it is necessary to perform the measurement on both left and right sides of a tank. Averaging the results eliminates an error resulting from the non-horizontal position of a reservoir (tank).

The features of carrying out the measurements of vertical reservoirs that do not provide access to the bottom part, is somewhat different from the order of measurement of horizontal tanks – the measurement of level is performed through a flange welded pipe.

One measurement cycle, including the site preparation for temperature sensor and antenna, their installation, calibration, and the level measurement itself do not exceed 1-1.5 minutes per tank (reservoir).
The energy – independent memory of the levelmeter and analyzer stores:
— more than 60 calibration tables, including those for virtually all types of railway tanks used in the former CIS.
— Data on the properties for more than 40 types of liquids.

The "knowledge base" of the device can be extended more than twice.
— Certificate of explosion proof equipment
— Application permit

Control system for weight and type of petroleum products

This solution is used when measurements of a large number of rail tankers are necessary. Operative account of the weight of petroleum products in train tanks on any part of the path, including those under the contact mains, control of the type and quality of petroleum products without opening a tank, without performing any in-laboratory analysis - is one of the most effective applications, which provides a rapid recoupment of the instrument.

For the control and accounting of transported petroleum products, for report generation according to the consignment note, the package includes a software ANALIQ, that installs on Windows OS computer.

Features of the solution

There are two main versions of the software for the levelmeter and analyzer ANALIQ-M:

The software version "Visible measurement" – the LCD display indicates the measurement results
The software version "Blind measurement" is designed to minimize the impact of human factors:
— The LCD display does not show any measurement results
— The display indicates the types and numbers of tanks, error messages and prompts for a user
— A search engine for tank number is implemented based on any amount of the last digits of its number

Before the beginning of measurements the computer program ANALIQ transfers a list of numbers and types of tanks that need to be measured in accordance with the invoice.

List of numbers and types of tanks

More than 100 calibration tables for railway and stationary tanks are stored in the non-volatile memory of the analyzer.

Regardless of the software version, the level analyzer enables to perform group memorization of all the measurement data and calculations with the subsequent issuance of those to the computer via RS232 / USB.

The report shows: the number and type of tank according to the invoice, the liquid level (mm), temperature (° C), density (g /cm3, 4 decimal places), volume (m3), weight (T, accuracy up to kg.), type of product, defined by the device (A76 Lysychansk, A95 Lukoil, DT winter-type Kremenchug, etc.), the level of produced water (mm). For a mixture of propane-butane the percentage of propane is shown.

Data received from the levelmeter ANALIQ-M is displayed in Excell format.

Level analyzers ANALIQ-S are used in enterprises that require continuous monitoring of various parameters of liquids (level, density, temperature, volume, weight, pressure and vapor mass). The use of our levelmeters is particularly effective for automation of technological processes of storage and handling of liquefied gases, ammonia and other corrosive, toxic, flammable, combustible or pressurized liquids in closed containers.

The objects of automation are storage tanks and loading-unloading racks that are supplied with systems of control and management of hazardous process parameters. Stationary levelmeters and analyzers ANALIQ-S are used to replace existing obsolete and worn out systems of level measurement - mechanical, submersible, radioisotope and others having immediate contact with the liquid or vapor. Level analyzers create an alternative for comparable in accuracy, but more expensive and demanding direct contact with liquid vapor, radar systems.

The levelmeter and analyzer Analik-S is installed next to each tank or loading-unloading post. Each levelmeter is equipped with two antennas: ultrasonic (acoustic converters AC), and a temperature sensor TS

Velocity antenna is used for measurement of response time from the opposite wall of a tank, whereas the level antenna measures from response time from the liquid surface.

The installation method for ultrasonic antennas and a temperature sensor on the outside wall of tanks of a railway train on the posts of loading-unloading racks, is magnetic. Special clamping devices for mounting on a stationary reservoir are supplied.

All units have individual numbers and are linked by a common pair of wires to a computer (Windows) or a microprocessor communication controller.

Software SCADA ANALIQ-MS has an intuitive interface and performs two main functions:
— Transfer to the nonvolatile memory of the device of a calibration table and a type of liquid to be measured
— Receiving the measurement results and their visualization.
Levelmeters can operate independently regardless of the presence of communication with the computer.
