Introducing MicroScan C HAPTER 1 1 > MicroScan is an ultrasonic, non-contact level measurement device of mono-block construction (combing the sensor and electronic components in a single unit). MicroScan provides reliable and precise level measurement results of both liquids and solids. It can be used for the following measurement tasks: Liquid tanks with calm surfaces Solids tanks that are dust-free MicroScan has a range of up to 5 m (16.5 ft) with an accuracy of approx. 0.25% within that range. MicroScan is available in two configurations: MicroScan with no display and no keyboard...

Introducing MicroScan C HAPTER 1 5 > Material Description Stainless Steel For liquid applications. High resistance in highly acidic and alcoholic environments. Less sensitive to echoes (in Solid applications). Coated Aluminum Designed for complex environments with problematic echoes, such as non-conductive vapors, solids or liquids. Good performance in problematic applications. High sensitivity to echoes. >

6 > MicroScan Users Manual Ensure that MicroScan is mounted in an area that meets the stated temperature, pressure and technical specifications. Ensure that high-voltage sources or cables are at least 1 m away from the sensor and its cable. Use a conduit connector that is either 1/2" NPT or M20x2.5 compatible (depending on the MicroScan model you have), to ensure the unit remains sealed. Use 26-16 AWG round wires for the MicroScanҒs electrical connections. Ensure that cables are routed correctly and tightened along walls or pipes. Installation and operation of this product should be...

Installing MicroScan C HAPTER 2 7 > When installing MicroScan, ensure that it is: Mounted above the dead-zone area. > NOTE: If the device enters the blocking distance (dead zone), it will not measure correctly. Positioned at least 0.5 m (1.64 ft) away from the tank walls. Perpendicular to the surface of the target. > NOTE: Even the slightest difference in angle may affect echo quality. size="-1">

8 > MicroScan Users Manual Placed as far as possible from noisy areas, such as a filling inlet. > MicroScan is available in two thread types, 2" BSP or 2" NPT. MicroScan can be installed with threaded-flange mounting or with thread-free flange mounting, as shown below: > Figure 3: Threaded Flange/Thread-Free Flange Mounting size="-1">

Installing MicroScan C HAPTER 2 9 > NOTES: When installing a thread-free flange mounted unit, you will need a 2" locking nut to secure the unit inside the tank. When installing a threaded flange, ensure that it matches the MicroScan threads. To install MicroScan: 1 Insert the threaded end of MicroScan into the aperture at the top of the tank or pipe. 2 Bolt MicroScan into place in one of the following ways: Threaded-flange mounting : Screw the unit into a flange with a threaded 2" hole. Thread-free mounting : Place MicroScan in the flange, and bolt it from within the tank with a 2" locking...

10 > MicroScan Users Manual If the level of the measured surface falls within the dead-zone area, you should use an extension pipe to mount MicroScan. When using an extension pipe, ensure that: The sensor is positioned in the center of the pipe. The pipe extension is parallel to the side/tank walls. The internal pipe diameter is at least 3" wide. When installing the MicroScan with extension pipes, follow these specifications: Pipe Length Internal Pipe Diameter 0.50 m (1.64 ft) 3" 1 m (3.28 ft) 3" > NOTE: It is always recommended to use interference signal feature (Pr.03) to locate...
