SG-TK complexes, modifications SG-TK-T (based on turbine gas meters TRZ, SG), SG-TK-R (based on rotary gas meters RVG, RABO) and SG-TK-D (based on diaphragm gas meters VK ), are designed to measure volume natural gas according to GOST 5542 and other non-aggressive, dry and purified, single- and multi-component gases in units of volume (quantity) reduced to standard conditions through automatic electronic correction of turbine (TRZ, SG), rotary (RVG, RABO), diaphragm (VK) meters gas by temperature and at fixed values ​​of pressure and gas compressibility coefficient.

For the SG-TK-D complexes, a measurement technique has been developed (Certificate of Certification of the Measurement Methodology No. 181-560-01.00270-2013) in accordance with which the relative expanded uncertainty of the SG-TK complex based on the VK gas meter with temperature correctors TS215 and TS220 does not exceed ±3%, which meets the requirements of GOST R 8.741-2011.

Principle of operation

Measuring complex SG-TK-D-40

The SG-TK-D-40 measuring complex takes into account natural gas consumption per industrial production and in commercial utilities.

The SG-TK complex operates on the basis of an electronic temperature corrector TS 220 and a VK diaphragm gas meter. The corrector brings the meter readings to normal conditions. The complex also includes a metering device designed for the expected highest gas consumption. If consumption is less than 40 m3/h, then BK G25 is used.

Temperature corrector TS220 from the company PromGazVolga TS-220 can work in tandem with the BK G25 meter. To do this, a mounting kit is placed on the input tube of the metering device.

It includes:

• temperature sensor sleeve (the corrector is placed in it, its position is fixed with a locking screw);
• union fastening nut for connection to the metering device.

On the other side, the installation kit is connected to the pipeline. The pulse generator IN-Z31 is attached to the reporting device of the meter using a clamp. It transmits pulses to the corrector input via a special cable. The higher the consumption, the more impulses.

What work does SG-TK-D-40 perform?

1. Thanks to the presence of an optical input, the device allows you to read and program information from the corrector.

2. On the screen you can see:

• measured quantities;
• values ​​normalized to normal conditions;
• archival data.

3. Based on measurements of operating gas pressure and air temperature, as well as calculated values, the device creates an archive. It can contain five hundred or more entries. Archive data interval: hour, day, month.

4. Recording in the archive occurs when:

• measuring the period ends,
• an accident happens
• change the corrector settings.

5. Allows you to program two digital outputs through which data is read from the complex at a distance.

6. Reports emergency situations:

• unauthorized access,
• changing the limits of measured quantities.

The corrector can be installed on the wall;

The temperature sensor is located on the housing.

SHORT DESCRIPTION

Measuring systems of the SG-TK-D types for measuring gas consumption are used in tasks requiring accurate readings of consumed natural (or other non-aggressive) gas. Typically these are commercial utilities and industrial systems. Thanks to the presence of a thermal corrector, the gas meter readings are updated taking into account the ambient temperature.

The SG-TK-D measuring complex consists of an electronic temperature corrector for gas volume TS220 and a diaphragm gas meter BK (VK). Depending on the planned flow rate, the kit includes a meter for the corresponding maximum flow rate.

The principle of operation of the complex is to simultaneously calculate the gas flow passing through the meter, taking into account automatic temperature correction based on the calculation by the TC220 corrector of the true flow reduced to standard conditions, using the values ​​of temperature, pressure and gas compressibility coefficient.
