Page 4: Safety
If the device is transported further, then only wrapped in the original packaging and protected against shocks and weather. Store the device in its original packaging in a dry place, sheltered from the weather, with humidity up to 85% without the effects of chemically active substances. Storage temperature range is from -20°C to +60°C. Level meters variants ULM–53_–02, 06, 10 are fitted with protective caps at the ultrasonic transducer to prevent damage. Before commissioning, remove the caps! ULM–53L © Dinel, s.r.o. -

Fig. 7: Level meter installation outside the influence of filling circulation j) In case the level of bulk-solid materials is measured, the measurement range is reduced. We recommend to consult the use with the manufacturer. ULM–53L © Dinel, s.r.o.
- Page 9 False surface reflections of the ultrasonic signal might result as a consequence of rotating mixer’s blades that ripple the surface level and thus cause unreliable level meter’s functioning (Fig. 12). p) The level meter should not be installed at places where ultrasonic signal false reflections caused by stirrer blades might occur (Fig. 13).

Page 10: Electrical Connection
Make the electric connection in voltage-free state! In case of strong electromagnetic interferences (EMI), parallel cable ducting with power lines, or when cable length exceeds 30 m we recommended to use shielded cable (for “I” and “U” variants only). ULM–53L © Dinel, s.r.o. -
