Economic factors of urban gas flowmeter selection
2021-04-25
The cost of urban gas flowmeter considers other costs such as procurement costs, installation and commissioning costs, maintenance, regular flow calibration costs, operation costs and spare parts costs.
Installation cost: Installation cost includes the cost of auxiliary parts such as stop valves and filters required for operation. Proper installation may require additional piping or bypass piping for regular maintenance.
Operation cost: the energy consumption at work, the internal power consumption of the electric instrument or the energy consumed to push the fluid through the instrument during the measurement process, that is, the cost of pumping energy to overcome the pressure loss caused by the measurement of the instrument.
Calibration cost: The flow meter of storage and transportation handover and business accounting must be calibrated regularly, considering the method and location of calibration and the inspection cost.
Maintenance fee and spare parts fee: Maintenance fee refers to the cost of maintaining the normal operation of the measurement system after the instrument is put into use. It mainly includes maintenance service and spare parts fee. The spare parts fee usually increases with the degree of improvement of the instrument performance.
Performance price ratio: the overall performance of domestic urban gas flowmeter is poor, and the technology needs to be improved; The performance of imported flowmeter is better; However, it is expensive, and it should be noted that the more complex the structure is, the less reliable it is.
