IP-68 Submersible Flow Meter
Built for harsh locations other meters fail: continuously dust-tight, permanently submersible up to 10 m depth, and powered by a 10-year internal battery.
Introduction
Engineered for flooded chambers, deep pits, and harsh burial sites.
Many pipeline monitoring points are located in outdoor underground valve chambers that flood during monsoons, or in remote desert pipelines with no electrical supply. Standard meters short-circuit, fog their displays, and stop logging. Bulfro’s IP-68 Submersible Flow Meter is hermetically resin-potted to survive complete underwater submersion up to 10 meters, powered by a 10-year internal battery that transmits flow data directly to the cloud.
Submersible Engineering
Hermetically Sealed Against Water Ingress
Water distribution networks and wastewater mains frequently run through underground valve pits that collect rainwater, runoff, and groundwater seepage. Standard IP65 or IP67 meters fail when water submerges their display covers.
Bulfro’s IP68 meter encapsulates all excitation coils, electrodes, and signal conditioning circuitry in heavy-duty polyurethane potting resin. Configuration is performed through the sealed glass window using an external magnetic wand.
Core Capabilities
Rugged Submersible Performance
Designed for water supply networks, flood-prone industrial pits, and municipal distribution mains.
10m Permanent Immersion
Continuous IP68 protection tested under 10 meters hydrostatic pressure. Keeps measuring through months of underground pit flooding.
IP68 Immersion Certified10-Year Lithium Autonomy
Powered by an ultra-low-power microprocessor and high-capacity D-cell lithium pack for up to 10 years of autonomous operation.
Up to 10 Years Battery LifeCellular Pit Telemetry
Supplied with high-gain remote pit antenna extending above ground level, transmitting flow logs reliably to the cloud.
4G / GPRS Pit AntennaBi-Directional Measurement
Measures both forward and reverse flows with high-speed sampling, ideal for municipal ring mains and balancing storage tanks.
Bi-Directional ±0.3%Empty Pipe & Tamper Alarms
Electrode resistance diagnostics immediately detect partially filled or empty lines, preventing false totaliser buildup.

Why Choose Bulfro IP68
Built to Survive Flooded Underground Pits
Zero maintenance solid-state construction designed for demanding field deployments.
Remote Pit Antenna
Even when the meter is buried deep underground in a flooded concrete chamber, the remote antenna extends above ground to ensure cellular connectivity.
10-Year Battery Freedom
Eliminates the cost of trenching power lines or replacing blown fuses after electrical storms. Operates maintenance-free for up to 10 years.
Hermetic Polyurethane Seal
Resin potting prevents humidity penetration, terminal block corrosion, and internal condensation fogging on display lenses.
Tamperproof CGWA Records
Meets all CGWA compliance conditions with non-resettable totalisers, reverse flow flags, and automated cloud report generation.

Frequently Asked Questions
Frequently Asked Questions
Find direct answers to common questions regarding IP-68 submersion, battery life, calibration, and pit antenna installation.
Yes. The entire sensor body and electronic converter housing are potted in solid industrial polyurethane resin and certified to IP68 rating under 10 meters of continuous water pressure. It is specifically engineered for valve chambers that remain flooded year-round.
The meter includes an optical/magnetic interface behind its thick tempered glass window. Operators use a handheld magnetic wand to navigate menus, change flow units, and adjust telemetry upload frequencies without opening the enclosure or breaking the waterproof seal.
The internal high-density lithium-thionyl chloride battery pack provides 5 to 10 years of autonomous operation, assuming a standard 15-minute measurement and telemetry upload schedule. Battery percentage is displayed on screen and transmitted to the cloud.
The unit is supplied with an IP68-sealed high-gain external antenna cable (3m or 5m length). The antenna mounts onto a small above-ground post or through a chamber lid grommet, guaranteeing strong 4G/GPRS signal transmission to the cloud.
Yes. Bulfro’s IP68 meter meets all CGWA requirements for industrial groundwater extraction. It features a non-resettable totaliser, tamper-resistant enclosure, bi-directional verification, and automated cloud reporting formatted for regulatory portal upload.
No. Because electromagnetic metering has zero moving parts or internal obstructions across the full-bore tube, pressure drop is equivalent to an identical length of straight pipe, saving pumping energy.
