Emergency & Standby Power Diesel Fuel Monitoring
For hospitals, telecom and utilities, the generator has to start when it's called on. Trendfuel gives you live ISO 4406 monitoring, alarms and proof-of-condition records so you can see exactly where your standby diesel stands — while single-pass filtration from our strategic partner DieselPure can bring it back into spec.
The problem
When the power fails, "probably fine" is not an answer.
A hospital, telecom hub or utility leans on its standby generator at the exact moment failure is least acceptable — and that generator runs on diesel that has been sitting for months.
Standby fuel degrades quietly between runtime tests. Water ingress, microbial growth and settling particulate push stored diesel past ISO 4406 limits, and by the time it matters, the generator may fail to start or take load. For these operators the stakes are regulatory and existential: emergency-power readiness is mandated and insured, and you are expected to prove stored-fuel quality, not assume it. Tank-level gauges measure volume, not cleanliness, and a periodic lab sample is already out of date. What these sites need is continuous evidence — proof of readiness they can hand to regulators, insurers and auditors at any moment.
Must start on demand
The generator carries the load the instant mains power drops. There is no second chance and no acceptable downtime.
Stored diesel goes off-spec
Water, microbial growth and particulate push fuel past ISO 4406 limits between runtime tests — invisible to tank gauges.
Regulatory & insurance drivers
Readiness is mandated and insured. Operators must produce evidence of stored-fuel cleanliness, not assurances.
The solution
Monitor, filter, alarm and prove — continuously.
Trendfuel turns standby fuel into a live, defensible instrument. Trendfuel's laser particle counters stream the ISO 4406 code (4–70 µm) to a secure cloud dashboard at sub-3-second latency — under 4 seconds round trip in most locations — while single-pass SAE J1488:2010 filtration from our strategic partner DieselPure takes stored diesel from 22/20/14 to 9/6/0 in a single pass. Warning and limit alarms fire over email and SMS, and every reading is stored securely so you can prove readiness to regulators, insurers and auditors at any time. Across 120+ global emergency-power sites running Trendfuel HMI/PLC control systems, and 12+ years of integration, this is readiness you can demonstrate, not just claim.
Proof
Readiness across 120+ emergency-power sites.
Trendfuel is part of more than 120 global emergency-power sites — including hyperscale data centers — with 12+ years of HMI and PLC integration, from single-tank pump control to complex multi-tank schedule-based filtration. The same platform monitors over 1 million litres of fuel distribution every week since 2020.
