Notes 1.Please make sure the measured media is compatible with contacting material; please pay attention to media density in the measurement (except water); 2. Polyethylene and polyurethane cables are optional and charged for materials and length; 3. If the product is installed in “lightning and thunder” area, please note “lightning-proof” in the order. We suggest to choose Lightning-proof Protection Device to protect transmitter. Please be sure good grounding as well; 2 4.Under standard conditions (4℃, g=9.80665 m/s ), the corresponding relationship between 1mH2O and 2 pressure is showed as...
