The hot water flow heat meter has the same features as the hot water boiler heat flow meter, but also has different points. The same thing holds that the hardware structure of the Ding meter is basically the same, and the temperature signals collected are the same; the difference is that the measurement object of the flow heat is different, and the hot water flow heat meter collects the inlet and outlet water temperatures. The main collection of three users of the return flow rate, the collection of these signals by the instrument conversion and numerical calculations, showing the cumulative flow of each user's value and cumulative effective heat value.
Whether it is a hot water boiler heat flow meter or a hot water flow heat meter, they have the advantage that the analog meter of the past cannot compare. Since the hot water is a single-phase fluid, its volume flow can be accurately measured, and the hot water density can be determined by measuring the hot water temperature, so that the hot water mass flow and heat can be accurately calculated. The advantages of these two types of instruments are their reliable performance, easy use, and direct readout of flow and heat values ​​through digital displays, unlike previous instruments. The reading also needs to be converted to know the true flow and calorific value.
The advantages of the hot water boiler heat flow meter and the hot water flow heat meter are that they can not only accurately display the main parameters of the hot water heating network system, but also reduce the primary measuring element and transmission device equipped with the meter, thereby reducing the number of The conversion of the signal has improved the accuracy of metering, while reducing the total cost of the instrument, with a set of economic and social benefits.
Sock Toe Linking Machines is used for sock toe closing of childrens and adults socks of every gauge.t
There are three kinds of Sock Toe Linking Machine:
1. Hand sock toe linking machine
2. Dial or round sock toe linking machine
3. Straight sock toe linking machine, which is most widely used. There are one motor sock toe linking machine, two motor sock toe linking machine, three motor sock toe linking machine, five motor sock toe linking machine, six motor sock toe linking machine according to different sock toe sewing effect. The later two kinds can sew the sock toe effect similar to hand sock toe sewing.
