At present, the heat metering market commonly used heat table is divided into mechanical heat meter(mechanical heat metering) and ultrasonic heat meter.The mechanical heat
meters is consist of temperature sensor, flow sensor and calculator. With the
aid of the temperature sensor, The mechanical Heat Meters measure the inlet
water and return water temperature. Flow rate sensor measures the volume rate
of the hot water in the tube trough the time difference. The figures recorded
will be delivered to integral calculator which calculates the total heat and
displays.
The mechanical heat meters
sensors measures the flow rate through the circles of the wheels. According to
the specification, The DN can be ≤40mm
and ≥50mm. According to the inner structure, the small size mechanical heat
meters can be single jet and multi jet. At present, our mechanical heat meters
belong to single jet mechanical heat meters and they have higher request from
the water quality. According to the counter of the flow sensor,
the mechanical heat meters can be dry and wet type. Our mechanical heat meters
are the dry type.Except mechanical heat
meters,the plastic heat meter is also a good product.

The hepatitis G virus (HGV) has been renamed GB virus type C (GBV-C) and is a virus of the Flaviviridae family, but it has not yet been assigned to which genus. Interestingly, there is some evidence that its co-infection with HIV-HIV can enhance the immune system of those patients in some way. However, Mughis Uddin Ahmed of King Abdulaziz Hospital (NGHA), Saudi Arabia, was concerned about the effect of the virus on the liver of otherwise healthy patients. He pointed out that since the FDA announced in 1997 that the virus did not cause human health problems, it did not screen the donated blood for this virus.
However, Mughis Uddin Ahmed has conducted a search of scientific literature over the past 16 years, which shows that the virus is very common around the world. In addition, there is also a correlation between the viral infection and hepatitis, cirrhosis, and it may also be related to hepatocellular carcinoma. Mughis Uddin Ahmed also found a significant correlation with hematological malignancies and bone marrow malignancies.
For this reason, he suggested that the virus should be studied to determine if it is a true human pathogen and a viral carcinogen. He also suggested that the virus screening of donated blood should be resumed immediately, instead of letting the medical staff continue to ignorantly infuse the virus with the recipient, in the event of transmission from the blood donor to the recipient with the hepatitis C virus. See the same morbidity and mortality risk until viral screening is adopted.
It is reported that the hepatitis G virus was identified in 1995. Several small studies have been conducted on the virus and the United States Food and Drug Administration (FDA) declared it a non-harmful virus in 1997. Researchers in Saudi Arabia published an article in the "International Journal of Immunological Studies," pointing out that current evidence suggests that this may be a wrong judgment. They claim that the viral transmission of donated blood that has not been screened by the virus, like infection by other means, has led to an increase in cirrhosis and liver cancer.
