Pipeline fluid properties associated with the effects of ultrasonic flowmeter and the instrument protection grade

RZ - in the installation and use 1158 c clip and RZ - type ultrasonic flowmeter 1158 w plug in the process of ultrasonic flowmeter, often have the customer inquiries about the nature of the medium in the pipeline that be measured is the likely effect on for measuring quantity, in fact in the instruction of measuring instrument of sample we provided, all are according to the ideal state of measurement results, we will meet in practical industrial production all kinds of working conditions, a lot of time is short of the ideal standard of measurement, but we can through some technical means to avoid the adverse factors in instrument measurement, in order to make the instrument measurement data results can meet the needs of our production. RZ - 1158 c clip and RZ - type ultrasonic flowmeter 1158 w insert type ultrasonic flow meter adopts the modular unibody design, independent menu operation, LCD backlight display. Protection grade reaches IP65 products transmitter, sensor to achieve IP68 protection grade, suitable for soaking wet, such as the use of harsh environments. For IP5 and IP8 protection grade exactly is a what kind of concept, related protection whether user need in production can be achieved in our help users in the process of installation and debugging, also often have such problems, user consultation today by embellish instrument technology co. , LTD. Of engineering and technical personnel will such standards tabulation, friends can use this table for IP protection have a clear understanding of the class. Q: particle size, particle content in the fluid, bubble content and electromagnetic effects on ultrasonic flowmeter measurement? A: medium type plug-in air clip-on influence & le; 3% ( Volume V/V) When & le; 1% ( V/V) When the particle impact & le; 0. 4% ( M/m mass ratio) , & le; 0. 2% ( m/m) When electromagnetic interference effects have influence to ask: how to understand the protection grade of ultrasonic flow meter? A: IP protection grade ( According to the EN60529 / IEC529) Protection grade IP68, IP to letters and Numbers for 6 * tag number first, 8 for two digital * first marking Numbers contact protection and foreign body protection level, the second tag Numbers waterproof protection level; Contact protection and foreign body protection level ( * first number) Waterproof protection level ( Two Numbers) * first digital protective range * first digital protective range name means name means without protection 0 0 1 protection for 50 mm diameter and more solid foreign body detector, ball diameter of 50 mm, should not be completely vertical falling water droplets into the water protection should not cause damage to the protective 12 2. 5 mm in diameter and more solid foreign body detector, ball diameter of 12. 5 mm, should not completely into the cabinet put oneself in another's position 2 15 degrees tilt, protective water cabinet put oneself in another's position to any side of the tilt Angle of 15 degrees, vertical drop of water droplets should not cause damage to the protective 2 3. 5 mm in diameter and more solid foreign body detector, ball diameter of 2. 5 mm, should not completely into 3 protection spatter of water to 60 degrees from the vertical line on both sides of the spatter water should not cause damage to the protective 1 4. 0 mm in diameter and more solid foreign body detector, ball diameter of 1. 0 mm, should not completely into four protective spray from every direction on the cabinet put oneself in another's position of hydraulic protection should not cause damage can't completely prevent dust into the dust, but the amount of dust will not cause harm to the equipment 5 protective water jet from every direction on the cabinet put oneself in another's position of water jet should not cause damage to the 6 dust when closed cabinet put oneself in another's position 20 millibars within low voltage should not enter the dust protection 6 strong water jet from every direction on the cabinet put oneself in another's position of strong water jet should not cause damage to note: the diameter of the probe should not through the protective cabinet put oneself in another's position of the hole 7 short-term immersion cabinet put oneself in another's short-term submerged under standard pressure, should not have to cause the damage of water immersion 8 protective long-term immersion can be submerged under certain conditions, should not have to cause damage of water immersion instrument technology co. , LTD. In this paper by embellish to sort out.
