To avoid delivery delays or process mismatches when replacing existing level units, verify these 4 parameters prior to order placement:
The cable-type probe on the Levelflex FMP57 can extend up to 45 meters (148 feet) with a maximum tensile load capacity of 30 kN, making it purpose-built for tall bulk solid storage bins and cement silos.
The FMP57 utilizes advanced Multi-Echo Tracking algorithms and Time-Domain Reflectometry (TDR). The guided radar pulse is directly constrained along the probe, making the measurement completely immune to airborne dust, filling noise, or thermal stratification.
The instrument is certified up to SIL 3 per IEC 61508 and holds comprehensive explosion-proof approvals including ATEX, IECEx, FM, CSA, and NEPSI for hazardous dust and gas environments.
Yes, the device features optional Bluetooth® wireless operation via the SmartBlue App, allowing commissioning, parameter adjustment, and Heartbeat diagnostic verification safely from ground level.
