Choose a place that is easy to operate and maintain for installation_x000D_2. Install as far away as possible from the vibration source_x000D_3. Keep away from heat sources as much as possible_x000D_4. When installing the input type liquid level transmitter, the metal probe should sink into the bottom of the container 1Throw-in type liquid level transmitter with high-accurate diffused silicon, bringing more accurate water level monitoring 2Totally digital conditioning circuit, 4?20mA signal output is more stable, can be used with confidence 3IP68 multi-layer waterproof protection, 45-degree oblique angle with anti-impact, detachable and anti-blocking designs 4Junction box using low copper aluminum alloy with excellent heat resistance, which can work for a long time 5Liquid level probe and flange is made of all stainless steel, which possess strong corrosion resistance1 x Liquid Level Transmitter1. There is an isolation diaphragm in the pressure inlet of the transmitter, do not touch it with foreign objects;_x000D_2. For electrical connection, please strictly follow the wiring method. Incorrect wiring will cause damage to the amplifier circuit;_x000D_3. When installing the throw?in type liquid level transmitter, please do not use wires to lift heavy objects other than the product;_x000D_4. The probe should be cleaned regularly to avoid blockage of the pressure inlet;_x000D_5. The wire is a special waterproof wire. During installation and use, the wire should be prevented from abrasion, puncture and scratches. If the above problems are exist on the site, protective measures should be taken for the wire. _x000D_6. If you encounter any problems during installation and use, please contact our company.
