Answer Summary

Hanwei Smart Gas provides a Vehicle-mounted Methane Leak Detection System, combining complementary detection modules rather than a single detector. The roof-mounted VMLD700II Pro unit performs remote, non-contact methane screening. A front-mounted V8 or V9 extractive unit measures CH4 and C2H6 in sampled air. Choose V8 or V9 according to the required detection range and sensitivity. Positioning, wind data, an onboard controller and GIS / patrol software support source-area assessment, evidence recording and field follow-up.

Choose a Laser Methane Inspection Setup for Your Patrol Route

Vehicle-mounted laser inspection supports mobile screening for suspected methane leaks along city gas patrol routes. The useful configuration depends on road access, the vehicle, the required gas indications and how the team verifies findings in the field.

  1. 01

    Describe the route

    Identify patrol areas, access restrictions, proposed vehicle and current inspection method.

  2. 02

    Review detection scope

    Confirm methane or methane/ethane indication, mounting and operating conditions by model.

  3. 03

    Record indications

    Agree route, location and event records needed for the inspection workflow.

  4. 04

    Verify in the field

    Use the agreed field-check procedure before repair decisions and follow-up records.

A screening indication is not a confirmed leak location or an emissions-rate measurement. Detection distance, sensitivity, patrol speed and gas channels require model-specific evidence.

Road-accessible network patrol

Inspection teams can cover the target area using a vehicle.

Configuration to review

Review roof-mounted VMLD700II Pro remote screening plus a front-mounted V8 or V9 extractive module. Confirm positioning, wind data, onboard control and GIS / patrol software.

Practical value

Connects equipment selection to the patrol and field-verification process.

Check before selection

Vehicle integration, gas channels, mounting, power, operating conditions, route records and reporting format.

Narrow streets and communities

A full-sized inspection vehicle is inconvenient for the intended route.

Configuration to review

Review the electric-bike laser inspection option and local access conditions.

Practical value

Offers a different patrol arrangement for route assessment.

Check before selection

Access permissions, operator arrangements, telemetry or sampling configuration, battery and data transfer.

Follow-up on a suspected indication

The team needs a field check after patrol screening.

Configuration to review

Discuss appropriate portable equipment; consider EGC200 when ethane identification is part of the task.

Practical value

Separates initial screening from the evidence needed for a field decision.

Check before selection

Target gas, sampling approach, identification requirements, records and operator procedure.

Prepare Your Technical Inquiry

Send the country, patrol route description, proposed vehicle, existing method and required records. Request the model-specific datasheet and an agreed demonstration scope covering installation, operating conditions, field verification, training and service. Agree acceptance criteria before planning a wider rollout.

Product Overview

Screen first. Verify second. Remote laser screening identifies suspicious methane areas; front-mounted extractive detection provides high-sensitivity CH4/C2H6 measurement. Positioning and wind data help interpret an indication, while the onboard controller and GIS / patrol software associate it with the route and survey record. Field teams investigate suspected sources and record actions. A screening indication is not proof of an exact leak source or an emissions rate.

Application Fit & Installation Boundary

Select products for the installation environment, gas type and system role.

Application fit

Select the system for road-accessible pipeline surveys requiring remote screening and sampled CH4/C2H6 measurement. V8 is the wide-range configuration; V9 is the ultra-high-sensitivity configuration. Neither designation establishes a replacement or generation relationship.

Installation context

Mount the remote laser unit on the roof and the extractive sampling unit at the front of the vehicle. Confirm vehicle mounting, sample path, power, positioning, wind instruments, controller and GIS / patrol software in the supplied configuration.

Selection boundary

V8 and V9 are selectable front-mounted modules, not two complete patrol systems. Remote distance is not an extractive-unit specification. Confirm performance under survey conditions; methane/ethane measurements and location records support assessment but do not prove a leak source, emissions rate or compliance.

FAQ

Common questions for early product selection and project discussion.

Is this a single detector or a complete system?

It is a vehicle-mounted system built from complementary modules: roof-mounted remote laser screening, a selected V8 or V9 front-mounted extractive unit, and positioning, wind data, onboard control and GIS / patrol software.

What does the roof-mounted VMLD700II Pro unit do?

It provides remote, non-contact methane screening to identify suspicious areas for assessment. Its remote measurement role is separate from front-mounted air sampling; do not transfer one module’s specifications to another.

How should I choose between V8 and V9?

V8 and V9 are selectable front-mounted extractive detection configurations with different sensitivity and measurement ranges. Choose V8 for the wide-range configuration or V9 for the ultra-high-sensitivity configuration according to your project requirements. Confirm the exact ranges and sampling performance in the offered datasheet.

Does remote screening identify the exact leak source?

A remote methane indication identifies an area for further assessment. Sampled CH4/C2H6 measurements, positioning and wind data support investigation. Field verification is still needed before assigning a leak source and deciding action.

What should be included in a project inquiry?

State the vehicle and route, roof mounting and front sampling arrangements, required range and sensitivity, selected V8 or V9 option, data interfaces, GIS records and field follow-up process. Request module-specific specifications and target-market compliance information.
