Abstract: the turbine meter scale in use should pay attention to some matters of information produced by excellent flow meter, flow meter manufacturer to offer you the quotation. Weinan and shunda meter manufacturers technical specialist on turbine flow sensor and display instrument of form a complete set of turbine flowmeter. Sensor has high precision, good repeatability, long life characteristics such as simple operation. Can be widely used in petroleum, chemical industry, metallurgy, paper making. More flow meter manufacturers choose model price quote you are welcome to inquire, here is the turbine meter scale in use should pay attention to some issues of the article details. Flow meter manufacturer technical specialist on turbine flow sensor and display instrument of form a complete set of turbine flowmeter. Sensor has high precision, good repeatability, long life characteristics such as simple operation. Can be widely used in petroleum, chemical industry, metallurgy, paper making industries such as measuring the volume of fluid transient flow and the total volume. Technology below small make up remind users should pay attention to in the turbine flowmeter using the following items: 1: the transmitter use a metal shielding wire power cord, ground to a good and reliable. Power supply for dc 24 v, 650 & Omega; Impedance. 2: the transmitter should be installed to avoid vertical installations, and ensure its have to adapt to straight pipe before and after, generally in the first 10 d, 5 d. 3: to ensure that the fluid flow direction and the direction of arrow instrument shell, shall not be installed backwards. 4: corrosion can not be made for turbine measured medium, especially the bearings, otherwise measures should be taken. 5: pay attention to the induction part cannot collide. 6, instrument installation use flange connection, threaded connection and clamp type; 7, the liquid flow direction when installation should direction of arrow and indicating flow sensor shell, and straight pipe upstream should & ge; 10 dn, downstream straight pipe should be & ge; 5DN( DN for pipe diameter) 。 8, sensors should be far away from the external magnetic field, such as can't be avoided, necessary measures should be taken; 9, in order to not affect the normal delivery of the liquid, maintenance should be straight section on opposite sides of the sensor installation outside the by-pass pipe; 10, sensors, outdoor installation time, please prepare amplifier plug waterproof processing; 11, sensor and display instrument connection, should according to the power of the amplifier to choose connection mode, see the relevant & other Instructions & throughout; At the same time remind users to regular maintenance and maintenance to ensure normal and accurate operation of the turbine flowmeter. 1, if it is a new liquid turbine flowmeter ( Half a year) Itself, eliminate flowmeter malfunction, check around the strong magnetic field, fluid is stable, Instability can be mounted to the rectifier) 。 2, if it is more than half a year's liquid turbine flow meter, or measuring medium not clean or corrosive, might have some bearing wear, should be in the upstream flow meters installed filters, change the internal impeller turbine flowmeter. And the need to calibrate, because the repeatability of turbine flowmeter is in commonly after half year will not be able to keep the factory. 3, uneven distribution of flow velocity and the existence of the secondary flow is one of the important factors affecting turbine, therefore, to ensure the straight pipe before and after 10 d, upstream downstream 5 d, to eliminate the secondary flow, should be equipped with rectifier. 4, turbine have higher request for the purity of the fluid, in front of the meter equipped with filter can guarantee clean fluid. 5, to ensure that the fluid is single phase, when necessary, the upstream flow meter installed gets over, for easy vaporization of liquid, downstream of the flow meter should guarantee of back pressure, the size of the back pressure can zui large traffic flow sensor under the pressure of 2 times the zui measured liquid under the high temperature steam pressure of 1. 2 times. Flow meter manufacturers insist & other; Science and technology, innovation, quality, service & throughout; The development of policy, continue to uphold & other; Make industry aircraft carrier, contribution to national economy & throughout; Purpose, to high-quality products, preferential prices, excellent services actively participate in market competition, we sincerely with friends from all walks of life, new and old customers sincere cooperation, create brilliant. Above is all there is in this article, you are welcome to inquire me manufacturer flowmeter selection, quotation, etc.
Sincerity can also foster research that is more useful and influential in society at large.
Helping our customers manage document workflow and increase efficiency through best-in-class mass flow meter and services. Fostering the growth and development of our employees.
Overall, mass flow meter may be a great way for manufacturers to expand their use of technology, but the price could present a significant hurdle for some businesses.
To offer abundant options of product is an important factor to a company, such as mass flow meterlow flow turbine flow meter to afford high-quality products for customers.
Apart from this, exhibit myriad fork density meter manufacturer benefits, like the prevention of vortex flow meter manufacturer by enhancing u shape coriolis mass flow meter.
