Sisson automation SISEN steam vortex flowmeter three-wire pulse output board 1, by the DIP switch settings to adapt to various calibers and various measuring medium 2, with 12 ~ 24V optional external power supply 3, pulse output: High level ≥ 8V (supply voltage -1V) low <0.5V 4, including pull-up resistor 1K5 open collector output Sisson FLVJ steam flow: straight pipe requirements: 1, steam flow meter must be mounted horizontally in the pipeline (pipeline tilt at 5 or less) steam flow meter manufacturers, wholesale, when installing the meter should axis concentric with the pipe axis of saturated steam flow meter manufacturers, the flow to be consistent. 2, the meter should be not less than the upstream pipe length straight pipe section 10D, etc., if the installation site promises recommend charging straight pipe upstream of 20D, downstream of the 5D. Of the bypass pipe requirements: In order to ensure the steam flow meter for maintenance without affecting the normal medium of steam flow meter manufacturers in the pipeline before the meter shut-off valve should be installed (valve) to produce steam flow meter manufacturers, but should be set bypass pipeline. Flow control valves to be installed downstream of the meter, the meter is used for cut-off valve must be installed upstream of the open, to avoid the upstream portion of the fluid flow phenomena produce instability. Steam flow meter manufacturers, wholesale, Sisson (certified), steam flow meter manufacturers to provide by Guangzhou Sisson automation control equipment Limited. Automation Equipment Co., Ltd. Guangzhou Sisson (www.sisenauto.com) is Guangzhou, flow meters leaders, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. Guangzhou Sisson automation leadership with the staff warmly welcome all inquiries negotiations to create automated Guangzhou Sisson a better future.
