On the morning of the 13th, the Jiangsu Provincial Price Bureau announced that it would raise the prices of refined oil products starting at midnight. This decision followed a notice from the National Development and Reform Commission. In Nanjing, the price of No. 92 Suwu gasoline increased from 7.73 yuan to 7.77 yuan per liter, marking the eighth price hike this year.
After the adjustment, the price of No. 89 Suwu gasoline in Nanjing went up from 7.29 yuan to 7.33 yuan per liter, while No. 92 gasoline climbed from 7.73 to 7.77 yuan. The price of No. 95 Soviet gasoline also rose from 8.16 to 8.21 yuan, and No. 0 diesel increased from 7.22 to 7.27 yuan per liter.
According to Zhongyu statistics, the wholesale price of gasoline in Nanjing has been on the rise since late November. For example, the wholesale price of No. 92 Suwu Petrochemical has increased by 150 to 200 yuan per ton, reaching 9,475 yuan per ton. Analysts believe that the disruption in Libya’s oil production and the high Brent crude oil spot prices during this valuation period have contributed to the steady increase in domestic refined oil prices. As a result, many gas stations in the city have seen a slight improvement in their profit margins.
The reporter found out that currently, only a few Sinopec gas stations in Nanjing, such as Shuizuo Kong and Dafangxiang, are offering discounts. The discount is around 5 cents per liter, which is still relatively small compared to the overall price hikes. Chemical Industry Mass Flow Meter
Sealand is a professional supplier of Chemical Mass Flow Meter, Chemical Mass Flowmeter, Chemical Flowmeter, Chemical Flow Meter, Chemical Coriolis Meter, ATEX, IECEx & CE approved.
The meter can work with a pulse receiver(Count). The connection is as follows. The
resistance value is up to the cable length & the max. input pulse frequency of receiver.
Current 10mA is suitable for most receivers; however, you can reduce the resistance value
when the cable is long. The max. current could be 50mA. Please use the fixed frequency
output function to check if the cable length & resistance value is suitable.
Please check following items before operation, and operate according to relevant rules.
a) If the meter is damaged during shipment and installation;
d) If the meter is grounded properly.

b) If the voltage is same as marked on nameplate;
c) If the fuse is correct;
e) If the Meter SN on the nameplate of sensor and transmitter are the same.
If everything is fine, please open all valves, make the pipeline full of liquid and then power on
the meter for warm-up for 20min before operation. Finally, conduct zero calibration after first
start, and shall do it again if the meter is moved to another site.
Preparation for zero calibration:
a) Power on the meter for approximately 20min for warm-up;
b) Run the process fluid through the sensor until the sensor temperature reaches the normal
process operating temperature.
c) Close the shutoff valve downstream from the sensor.
d) Ensure that the sensor is filled with fluid and the process flow has completely stopped.
