Choosing a level technology
Choosing by medium
| Technology | Type | Best for |
|---|---|---|
| Radar | Continuous, non-contact | Liquids, vapour, dust, high temperature |
| Ultrasonic | Continuous, non-contact | Water, wastewater, open tanks |
| Capacitance | Continuous / point | Liquids, boiler water |
| Differential pressure | Continuous | Boiler drums, pressurised tanks |
| Rotary paddle | Point | Solids silos: coal, feed, cement |
| Float, electrode | Point | Water tanks, feed pumps |
Level instrument standards
| Standard | Scope |
|---|---|
| EN 12952-7, EN 12953-6 | Boiler water level equipment |
| EN 302 372, EN 302 729 | Level probing radar |
| 2014/53/EU (RED) | Radio Equipment Directive for radar |

| EN 60529 | IP65 / IP67 / IP68 enclosures |
FAQ
Radar or ultrasonic?
Ultrasonic is cheaper and suits clean water in open tanks. Radar is unaffected by vapour, temperature, pressure and dust.
What for boiler drum level?
DP or capacitance for continuous level, with an independent low-water limiter per EN 12953-6.
