Details shows that the U.S. SIERRA meter, SIERRA meter manufacturers, SIERRA meter price 
 640S and 620S series heat flow meter connected to the process of compression sleeve when the low pressure line insertion devices, high-pressure unit and flange connections online insertion and removal in four ways. Online insertion and removal device which enables users to maintain the instrument will not affect the drying process caused by the normal operation. 
 640S Series heat flow meter to provide isolation / non-isolated 4-20mA or voltage output demand 0-5V/0-10V/1-5V both high and low alarm outputs, dual range switch for the dry contact input. Instrument case has NEMA4X, IP65 and explosion-proof enclosure IP67 two, with and without local display with a display, there is one instrument, and install two split, split installation can be 30 meters away. 
 780S pipe heat flow meter 
 780S pipeline with a unique thermal gas flow meter fairing, effectively reducing the required straight run of pipe flow meter comes with fairing effectively eliminated due to lack of straight pipe flow caused by the uneven distribution, thus ensuring the use of the instrument accuracy. 780S thermal flow conditions in most of the straight pipe length can be reduced to three times the diameter. 780S meter process connections with ANSI, DIN flange connection, you can easily remove the sensor and the probe to maintain. 
 Straight tube to clean the sensor performance, easy maintenance 
 SIERRA 800 series with its known high stability of the sensors, sensor manufacturing platinum, platinum certification by NIST to the temperature change detection performance for the most reliable materials. Thus the precision of drift is reduced to a minimum. 
 SIEERA implement proprietary sensor with a larger diameter, because people usually complain about dust or particles blocking thermal micro-sensor measurements as particle impact. So many other functions do not have to clean the sensor diameter is too small or the thermal sensor accuracy and stability can not be guaranteed a long time. The 820S.830/840 model can be provided and large diameter sensor cleaning function for you to solve this concern. 
 Users can, under the guidance of the technical staff to provide quick access SIERRA diameter of 0.030-inch diameter of 0.031 inches for cleaning the sensor clean. 
 Mass Flow Meter 
 In addition to providing the steam mass flow rate, temperature and pressure direct reading instrument can also check meter accuracy, real-time calculation of peak demand for conflict resolution, billing history information access through a modem. Integrated flow meter and a computer modem provides an accurate, verifiable steam use to measure, reduce the billing and contract conflicts, to help energy managers to understand consumer trends and to control production costs.
