Product Specifications Product Name: asphalt meter diameter: DN15 ~ DN3000mm Nominal pressure: 0.6 ~ 42MPa conditions Temperature: 100 ℃ ~ + 500 ℃ Accuracy: ± 0.5 ~ ± 1.5% FS turndown ratio: 1:15 shell: Carbon; stainless steel (or by user request consultations provided) Power supply: Built-in lithium battery 3.6VDC (changed every two years, with no signal output); external supply 24VDC (band signal output) Output signal: 4 ~ 20mA wire; pulse 0 ~ 1000HZ ; RS232 / RS485 (or by user request consultations provided) Protection class: IP65; IP67 proof mark: intrinsically safe ExiallCT4; flameproof ExdllCT4 Executive Standard: Q / BET05-06 meter display: cumulative flow; instantaneous flow; working conditions temperature; pressure conditions (temperature and pressure compensation type only); rod percent of full scale; fault self Connection: Flanged Pipe; Wafer; plug-in; pipe taper thread type Note: See the meter installation size selection sample (download) Typical applications are mainly used in asphalt meter metering improvement on asphalt, coal tar and other viscous media Features * The whole instrument in the design with no moving parts, plug-in structure, easy disassembly * Can choose a variety of corrosion resistance and high temperature materials (such as Hastelloy, titanium, etc.) *, fully sealed machine can do no dead (welding form), without any leaks, can withstand high pressure 42MPa · instrument features self-test procedures, failure phenomenon glance ? Sensor is not in contact with the measured medium, there is no wear and tear parts, the use of safe and reliable use of dry · situ calibration method, which uses weights hanging weight method. One-touch operation can be completed with a variety of installation calibration · choose from, such as choosing the online plug-in, low installation costs * with optional low-cut, non-linear correction, filtering time selectable · accurate measurement accuracy of 0.2% * repeatability, generally 0.05 to 0.08%, rapid Pressure loss is small, only about a standard orifice 1/2 △ P · jamming, anti-impurity capacity particularly strong Can be based on the actual need to be replaced Baffles (target tablets) and change the flow range * Low-power battery-site display that can be read online direct indication, the display screen can be read simultaneously instantaneous and cumulative flow rate and percentage bar graph · Easy to install, easy to maintain ? Multiple output format, can Remote various parameters * Anti-shock resistance, within a certain range can be measured pulsatile flow Note: do asphalt laminated insulation type flowmeter
