Measurement of an expense unit
The main purpose:
- measuring the amount of flow.
The main equipment:
- flow meters (separate counters or measuring systems).
Depending on the desired type of flow accounting distinguish:
- commercial metering;
- operational (technical) metering.
Number of working measuring lines metering defined by the project.
For each group of measuring lines connected to one collector, provides a back-up measuring line.
For operational accounting provides a measuring line and bypass with a shut-off device.
- petroleum and petroleum products
- associated petroleum gas
- liquefied petroleum gases
- liquefied natural gas
- flammable liquids
- combustible liquids
- nonaggressive environments
- aggressive environment
Pressure: from 0,07 MPa to 25 MPa.
Temperature, °С: from -196 up to 350.
Electrical power system
Category reliability of power supply — I.
Supply voltage 380/220V, 12V lighting repair.
System of grounding TN-S.
Automatic switches conform to requirements of industrial safety of the Russian Federation.
On the object provides the following types of coverage:
- working lighting — 220V;
- emergency lighting — 220V;
- repair lighting — 12V (apply reducing isolation transformers 220/12V);
Electrical safety system
Electrical Grounding is made in accordance with the requirements of industrial safety of the Russian Federation.
To protect people from electric shock in the building all metal fine dead parts of electrical equipment are grounded in accordance with the requirements of industrial safety and also the system of equalizing of potentials is carried out.
The temperature of the indoor air block must comply with the technical requirements of the manufacturers of the equipment, systems, devices and instruments, but not less than +5°C and above +35°C .
Heating chamber block can be formed as by electrical heaters and water by means of heating.
The ventilation system is performed in accordance with the requirements of industrial safety of the Russian Federation.
Automatic Fire Suppression
The unit has the following performance:
- fire suppression contains the estimated amount of extinguishing agent available for immediate use in the event of a fire;
- installation supplies at least 95% of the estimated mass of extinguishing agent required to create a fire extinguishing concentration in the protected area, designed to extinguish a fire in a time not exceeding the normative;
- installation provides a delay of release of fire extinguishing substance to the protected placements on time;
- installation is automatic and remote starter types.
Gas contamination monitoring system
Gas contamination monitoring system consists of a secondary device and field sensors for the corresponding gas.
Gas contamination monitoring system is provided with the necessary number of sensors, taking into account the composition of the target gas (vapor).
The control device includes a measuring apparatus for displaying the current gas concentration for each sensor.
The device should have a lock function alarm and re-install.
