GE 36DL belongs to the professional deep penetration transducer lineup for challenging piping measurement conditions. Model definition: 36 stands for fixed low-frequency design optimized for thick pipe barriers; DL means Deep Long penetration performance oriented to fouled, corroded pipe walls. As the front-end signal acquisition hardware of transit-time ultrasonic flow systems, it transmits ultrasonic signals into pipe walls and receives reflected echo signals, then transmits valid waveforms to the DRC-100X signal processing board for flow velocity and cumulative flow calculation by the host CPU.

Its low-frequency piezoelectric wafer is specially screened and matched with high-efficiency acoustic matching and damping materials. Compared with conventional medium-frequency probes such as M27R, the 36DL ultrasonic beam can easily pass through thick carbon steel walls, internal rust layers, mineral scale, paint coatings and liner materials, effectively solving common field faults including weak echo, signal loss and violent flow value fluctuation on aged industrial water pipelines. The internal impedance is precisely calibrated to match the circuit characteristics of original GE flow hosts, lowering ultrasonic energy attenuation during wall penetration and greatly improving the system signal-to-noise ratio under harsh pipe conditions.

The transducer contact face adopts ultra-wear-resistant solid composite material, bearing long-term clamping pressure from P1392 fixtures and frequent disassembly during maintenance without surface wear or depression. The fully sealed enclosure meets IP65 protection rating, resisting dust accumulation, condensate splashing and mild chemical vapor erosion in humid pump houses, outdoor pipe racks and chemical instrument areas. Internal signal wires adopt double-layer copper braided shielding structure, which isolates electromagnetic interference generated by on-site inverters, large motors and high-voltage power distribution circuits to maintain stable waveform output.

Adopting non-intrusive external clamping installation mode, the 36DL requires no pipe cutting, drilling or production shutdown during installation and overhaul. It creates zero pipeline pressure loss and zero medium contamination risk, perfectly matching the continuous operation requirements of industrial production devices. The standard built-in connector is fully compatible with GE original shielded cables 710-1247 and PWO6J8-4S for plug-and-play wiring deployment on site. Matched with 25998 or 399857-PR acoustic couplant, it eliminates air gaps between probe and pipe surface to guarantee efficient acoustic conduction.

Every finished GE 36DL transducer undergoes echo amplitude testing, impedance calibration and high-temperature aging burn-in inspection before factory delivery to ensure unified sensitivity and frequency parameters across production batches. No mechanical wearing parts exist inside the probe assembly. Routine maintenance only includes regular inspection of couplant aging state, fixture fastening tightness and cable sheath integrity, with low long-term operation and maintenance costs for users.

Typical application scenarios cover municipal large-caliber water supply trunk lines, thermal power plant circulating water systems, sewage treatment pipelines, chemical factory process water delivery and heating network hot medium flow monitoring. It is the preferred probe for difficult measurement working conditions with thick walls and severe scaling, improving the environmental adaptability of GE clamp-on ultrasonic metering systems.
