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.
Hujiao strong daily limit plastic market change days?
On the 19th, Shanghai Tianjiao's main contract reached a strong daily limit, triggering high market attention. Due to the deterioration of Sino-Vietnamese relations, more than half of Vietnamese rubber exports to China have led to rumors. Along with rumors, the fundamentals of rubber are changing quietly. As of the close on the 19th, Shanghai Tianjiao’s September contract price was 14,550 yuan/ton.
The rubber market has changed? The ever active natural rubber market is no stranger to the ups and downs. Looking at the historical data, several daily limit and subsequent trend of natural rubber in the first quarter of this year: February 17 Hujiao daily limit closed at 16,400 yuan / ton, followed by a drop of nearly 2,000 points in two consecutive weeks, March 11 and March 12 Daily plastic daily limit for two consecutive days, followed by a lower limit on March 17 and a month later on April 23 set the lowest closing price of 13,755 yuan / ton.
“Some people interpreted the sharp increase in natural rubber as a stalemate between China and Vietnam and prompted the funds to overheat. This, I think, is neither appropriate nor sufficient. This situation in China and Vietnam does not mean that today or the weekend occurred. Why does the fund happen? Why is this topic being hyped today?" analyst Bai Hu said.
With Vietnam's domestic war against Chinese companies and the continued bruising of Chinese citizens, the Chinese government has decided to suspend the implementation of bilateral exchanges and increase the level of promptness for Chinese citizens traveling to Vietnam. It will also take the situation as the situation develops and study further measures. It is worth noting whether or not it will affect Sino-Vietnamese trade, but there is no clear news at present.
Even if China did not set aside a ban on Vietnamese rubber exports to China, the amount of Vietnam's rubber exports to China is also shrinking. According to data from the Ministry of Agriculture of Vietnam, Vietnam's rubber exports amounted to US$292 million in the first quarter of this year, a decrease of 42% from the same period of last year. Moreover, the Vietnam Rubber Association has been calling for the cancellation of 3% of rubber export tariffs to stimulate the export of rubber.
Vietnam's rubber exports to China have shrunk sharply, and China’s port inventories have continued to expand. According to data released by the General Administration of Customs of China, from January to April, China imported 1.58 million tons, an increase of 14.5% year-on-year. As of May 15, Qingdao Rubber Bonded Zone rubber stocks increased again, with a total inventory of 362,200 tons, a record high. At the same time, Japan's natural rubber stocks at the port were 21,800 tons, which also remained high in recent years.
In May, domestic and foreign rubber plantations ushered in the rubber season. At present, China's Hainan and Yunnan's natural rubber are fully opened, and northern and central Thai production areas are also fully open. IRSG, the International Rubber Research Organization, said that the global natural rubber supply surplus in 2014 will be more than three times higher than previously estimated, reaching the highest level in 10 years. In December last year, the organization expects the surplus to be at most 241,000 tons, and the current estimate exceeds 714,000 tons, and there is still the possibility that the future production figures will increase.
The continuous decline in natural rubber prices and the expected large output have led to a sharp decline in the production enthusiasm of plastic farmers. According to Zhuo Chuang's recent research in a plastics factory in Yunnan, since the Songkran Festival, the output of local dry glue declined by 30% to 70%, and Hainan's natural rubber production area has already been converted to latex. The enthusiasm for dry rubber production is very low. At present, there are still many rubber factory dry glue production lines still not started. At the same time, the main producing areas in Southeast Asia are also facing a situation of reduced production.
The continuous decline in the price of natural rubber makes it equal to the price of chemical rubber. According to Treasure Island statistics, the current price difference between latex and styrene-butadiene rubber is zero. The trend of synthetic rubber and the trend of natural rubber have been out of line recently. The drop in butadiene price is limited. PetroChina and Sinopec basically maintain the ex-factory price of synthetic rubber, making the price of synthetic rubber weak and the price of natural rubber gradually falling to the price of synthetic rubber. Hold steady.
Analyst Zhao Lei believes that in the case of zero spread of latex and styrene butadiene rubber, the digestion of natural rubber stocks will be greatly accelerated. The latest published weekly inventory report shows that the inventory of natural rubber warehouses is 123,600 tons and the total inventory is 163,100 tons, of which the warehouse receipt inventory has fallen by 40,200 tons, a decrease of 24.55%, from the highest point created in February. At the same time, despite the fact that the inventory in Qingdao Free Trade Zone is still operating at a high level, the growth momentum in recent months has obviously slowed down. With the future high levels of import volume falling, the bonded area stocks have a chance to decline, and the destocking cycle begins.
Zhao Lei reminded that the long-term turning point of the natural rubber market needs fundamental support, while the fundamentals such as Thailand's throwing of storage and the decline in the operating rate of downstream tire plants will all constrain the growth of natural rubber. Only the change in the supply pattern can substantially boost the day. The trend of plastic, so the current trend of natural rubber will be repeated, investors cautious operation.
