Product Description OverviewFlow switch is a kind of measurement instrument which could real-time monitor the liquid and air flow in the pipeline, and output signal at the same time.This product adopts all metal case, no moving parts, the switch quantity can be continuously adjustable, pressure loss is small, compact structure, a plurality of LED real time display of flow state and the state of the switch. Easy installation, suitable for a variety of diameter of product requirements, can be used to monitor the fluid in the pipeline flow, stop idling protection monitoring or prevent pump. Widely used in the hydro-power industry, industrial hydraulics of flow monitoring.Special features1.All stainless steel shell, no moving parts, no need for any interference2.Easy installation, suitable for various pipe diameter requirements3.Switching output, adjustable on-site connection of control points4.LED real-time display of flow status and switch statusTechnical DataProduct codeQDB118Measure range3~300cm/s(Liquid) 200~300cm/s(air)Power supply24±20%VDCCurrent consumption:<90mASignal outputRelay(SPDT)/PNPTransistor characteristicsSwitch voltage24±20%VDCSwitch current≤1.2AThe relay characteristicsSwitch voltage≤250VAC/30VDCSwitch current≤3AThe initialization timetypical value 8s(2~15s)Response timetypical value 2s(1~15s)Temperature gradientmax250oC/minProtectionIP67Medium temperature-20~80oCAmbient temperature-10~70oCStorage temperature-20~85oCPressure rating10MPaProbe materials304/316 stainless steelHousing material304 stainless steel Product applicationSensing components and the signal processing unit of the product is a whole structure, set up to monitor the flow of continuous adjustment, the monitoring range and velocity, and has nothing to do with the overall flow or velocity. This product is used for monitoring the following aspects:(1)Medium flow / reduce the flow rate;(2)Media presence / absence;(3)Medium flow / stillLights in 6 different colors on the panel shows the alarm status and the trend of velocity, and output switching signal through the single relay.The 6 indicator is defined as follows:1.1 red indicator lights: Not reach the setting velocity. 2.1 yellow indicator lights: Reach or exceed the set flow rate, the relay start running.3.4 green indicators:When the flow rate exceeds the set flow rate, the indicators would lights in turn from left to right. When the flow rate slows down, the indicator would dies in the opposite order.Structure and electrical definitionsM12*1 The definition of connectionElectrical definitions--The wiring diagramInstallation1.To install the product, the probe need to be fully immersed in the fluid, if install to a tube with small diameter, please pay attention to avoid push the probe on the tube wall.2.When the fluid can not be completely filled pipes, product to be installed at the bottom of the tube.3.If the pipeline has sediments, please install the product at the side wall of the pipe, horizontal installation, to avoid air and sediment4.Install the product in a straight or curved intersection distance, pipe length should not less than 4 times the diameter of the pipeline.Product regulationAfter install the products on the pipe, please connect the wire connection according to the electrical definition. Switch on the power, then adjust product after 2 minutes. As shown in the picture above, screw off the anti-dust screw, then we could see the adjustment point of potentiometer. Standing at the cable entry side, rotate the adjustment point in clockwise, the indicator would lights from left to tight in order, light off conversely.For different applications, follow the steps below to adjust, If the adjustment effect is not ideal, it can be repeated for several times.NOTE:When the velocity of fluid flow changes from 15 to 30 seconds, then adjust the potentiometer.1.Medium flow / reduce the flow rate a.Set the minimum flow rate or the standard flow rate lower than the set monitoring flow rate b.Adjust the potentiometer, make the right indicator LED lights c.Restore the monitoring flow rate, adjust the potentiometer, make the yellow indicator lights and at least one green indicator lights2.Media presence / absence Adjust the potentiometer, when the pipeline medium does not flow, make the red indicator lights, when the medium flows, make yellow and at least one green indicator lights.3.Medium flow / stillAdjust the potentiometer, when there is no medium in the pipeline, make the red indicator light on, when there is a medium in the pipeline or there is a certain flow rate, make the yellow and at least one green indicator light on.Attention1.You should read this manual carefully before use, correct wiring.2.Before turning on power supply voltage on the product, confirm the power supply range, high pressure could damage the product;3.Pay attention to direction & method of installation.WarrantyFrom the date of delivery within a year, the company has quality defects caused by material and technology problem free replacement or repair of product; product failure caused by the use of the process of non quality reasons, the company responsible for the repair, only charge the cost of the material.Please use the machine comply with the User Guide.Company Profile Explosion-Proof Certificate FAQ1.
