Case Study: Dublin Warehouse Operations Manager Sourcing Success
Sarah Bennett, a Warehouse Operations Manager in Dublin, opened the sourcing file with three fixed points: real certification documents, stable lead times and one engineering contact who answers the phone.
Wage costs in Ireland made installation labour the largest line item, which redirected the buying conversation in Dublin towards products that cut install minutes.
Sarah Bennett scored the shortlist on landed cost per installed point, not on unit price in isolation. Sarah Bennett signed off the first Radar Level Sensor for Foam Tank order covering 9 sites in Ireland, and the specification sheet was rebuilt around the reference standards rather than around a brand name.
Sarah Bennett ran the pilot for 10 days and measured cost per installed point instead of cost per carton. The scene repeats across older estates in Dublin: fifteen-year-old loop wiring that cannot be replaced this year, so every new head has to live on the old protocol and panel.
Problem Analysis & Field Report: Why Global Importers Need Radar Level Sensor for Foam Tank
Most buying mistakes in this category are documentation mistakes, and they surface at inspection rather than at delivery.
A fire water reserve tank in Dublin was read by dipping, which was skipped every winter until a low level alarm finally fired.
Field case: The foam store in Ireland was re-specified with microwave radar and has run 3 months without a reading fault.
- Non-contact measurement puts no moving part inside the tank
- Radar versions handle foam covered or vapour heavy surfaces
- IP67 head survives a flooded chamber event
- Modbus output removes the need for a separate converter at the BMS

Fire Protection Equipment OEM Process: From Inquiry to Shipment
Working with a direct factory changes the order sequence in useful ways: the documents come before the money. A standard OEM project then follows 8 steps:
- Tell Us Your Target Market - North America, Latin America, EU, UK, Oceania, Middle East, Southeast Asia, South Asia or Africa; each market runs different certification routes, language sets and audit expectations
- Select a Product Platform - our team recommends suitable configurations according to your service format, target customers and replacement cycle plan
- Verify Documentation - request the relevant CE file, EN 54 series aligned construction papers and FCC compliance documentation where applicable, then check the notified body reference
- Confirm OEM Requirements - housing, logo, part numbers, languages, packaging, manuals and accessory sets
- Sample Evaluation - sample units can be field tested by your technicians before commercial terms are agreed according to the agreed conditions
- Confirm Production - after specifications, commercial terms and OEM details are confirmed, the project moves into the production slot
- Quality Inspection - units are inspected with chamber response, threshold and batch cycle procedures according to applicable production and quality control standards
- Shipment - goods are prepared for shipment FOB, CIF or DDP according to the agreed logistics requirements
Customer Testimonials
Comments collected after the first full year of each partnership.
- Thomas Eriksen (MEP Consulting Engineer, Madrid, Spain): "Replacement heads arrived on the old loop protocol, so we avoided rewiring the whole Madrid block."
- Kenji Watanabe (Fire Safety Distributor Owner, Sao Paulo, Brazil): "Our operators only noticed the change because the service van now carries one family instead of four."
- Sarah Bennett (Warehouse Operations Manager, Dublin, Ireland): "Spare bases and covers arrived in three weeks when a renovation crew damaged stock, which kept our Dublin contract on schedule."
Frequently Asked Questions
Q: Why use a non-contact level sensor in a fire reserve tank?
A: Nothing sits in the water, so nothing fouls, and the reading stays stable across years with sediment build up. It also avoids any potable water contamination question.
Q: When is radar better than ultrasonic?
A: Radar suits foam covered or vapour heavy surfaces where ultrasonic echo gets absorbed. The trade off is unit cost against the consequence of a wrong tank reading.
Q: How much dead band is there?
A: Under 0.3 metres from the sensor face. Mounting height and the overflow level decide the real usable range, so both are checked before the order is confirmed.
Q: Can it be read by our building management system?
A: Yes. The 4-20 mA loop connects to a standard analogue input, and the RS485 Modbus RTU version gives a digital register set to most BMS gateways.
Q: What MOQ applies to level instruments?
A: Evaluation units start at 2 pieces. Distributor orders start at 50 units and OEM labelling plus custom scale printing starts at 200 pieces.
