Gas Flow meter | Gas Metering System | AutoPilot Pro | USA

AutoPILOT PRO measuring systems

designed for measuring flow, volume, temperature, pressure and pressure difference, as well as measuring and converting output electrical signals from flow, temperature, pressure and pressure difference converters into physical quantities and calculating the volume and volume flow of natural gas, reduced to standard conditions in one or more pipelines.

The system consists of a computer case with a display and keyboard and AutoMITTER PRO touch modules. Inside the computer case there is a microprocessor, non-volatile memory, an internal battery and devices that process input signals from primary converters and generate output signals. Depending on the application conditions, the computer case can be made of fiberglass or metal.

Structurally, the sensor module can be made in a separate housing (spaced version) or be in the same housing with a calculator (built-in version). The number of built-in sensor modules in the system is not more than one, sensor modules in a spaced version is not more than four.

The sensor module includes:
- converter of static pressure (absolute or excessive) into a digital signal;
- pressure difference converter to digital signal;
- analog-to-digital signal converter for resistance thermal converter and Pt 100 resistance thermal converter of class A or B;
- microprocessor.

Sensor modules, depending on the measured static pressure, can be manufactured in the versions MXA 125, MXA 145, MXG 170.

The principle of operation of the system consists in measuring and converting the output electrical signals from flow, temperature, pressure and pressure difference converters into values of physical quantities or measuring temperature, pressure and pressure difference and calculating the volume and volume flow of natural gas reduced to standard conditions (temperature 20 ° C and absolute pressure 101325 Pa).

The results of measurements and calculations can be displayed on the system display or transmitted to higher-level systems.

The system has an archive for storing daily or hourly measured and calculated parameters, archives of events and errors for a maximum of six pipelines. The total number of records in the system archive is up to 5400.

With the help of a personal computer connected to the system and AutoConfig software, its configuration can be performed.

The digital identifier of the software is not displayed on the LCD of the system. Self-diagnosis is carried out to monitor the operation of the system. To protect against unauthorized access to the system software, access to the system settings is limited by a password and seals.
