oil flow meter,digital flow meter,high temperature meter,high pressure flow meter 2008 Improved type target Flow Meter SBL digital target flow meter is proprietary product independent created by our company, and is warmly welcomed by customers in the last past 10s years. It suit for market very much. After combine microcomputer optimization and structure rationalization, we launch grandly 2008 upgrade version in 2009, which has a wider adaptability,Higher reliability and wider flow range for target flowmeter:liquid measuring range can up to 1:200 times, gas can up to 1:100 times,steam can up to 1:30 times.in the past,our flow meter can resist temperature from -196℃~450℃。But now,can resist from -196℃~700℃。The minimum measure flow ,in the past is 50L/h,now 2L/h is ok for liquid.and the gas,in the past the minimum measure is 3m3/h,but now can measure 0.02m3/h.and the maximum pressure can up to 55Mpa.and We have a large inspection system to make sure our quality and accuracy. Technical parameters: Nominal diameter：15~3000mm Nominal pressure：0~55Mpa Media temperature：70℃~+200℃（high temperature）-196℃~+700℃（Extreme temperatures） Accuracy class：0.2；0.5；1.0 Range degree：1：3 1：5 1：10 1:20 1:30 Connection type：pipeline flange type Shell Material：Carbon steel；304；316L Working Voltage：Built-in 3.6V lithium battery, 24VDC Output Signal：4~20Am，pulse，0~10V，RS232/RS485，Hart Protocol Protection class：IP65; IP67; IP68 Explosion-proof grade：Intrinsically safe type (ExiallCT4); Explosion isolating type (ExiallBT4) Executive Standard：Q/QZRX001-2007
