Case Study: New York Construction Procurement Manager Sourcing Success
The procurement team behind Thomas Eriksen in New York shortlisted three factories on one condition: whoever answers the chamber and threshold questions with numbers gets the order.
Public tenders in United States now score the documentation pack alongside the unit price, so the cheapest bid without test reports loses on the evaluation sheet.
What settled it was boring. The factory answered the threshold question in writing with a number, and the other two did not. Thomas Eriksen signed off the first Level Gauge Ultrasonic for Fire Water Tank order covering 29 sites in United States, and the specification sheet was rebuilt around the reference standards rather than around a brand name.
From first enquiry to confirmed purchase order took 11 days, with half of that spent on certificate verification rather than commercial terms. For a distributor in New York the decision meeting is short. Two columns on one page: landed cost per unit against the risk of a rejected inspection.
Problem Analysis & Field Report: Why Global Importers Need Level Gauge Ultrasonic for Fire Water Tank
The question every Construction Procurement Manager asks too late is simple: what happens in year three when nobody stocks spares for this range?
A foam store in United States defeated two ultrasonic heads in a row because nobody modelled the foam layer on top of the liquid.
Field case: The foam store in United States 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
The process below is the one our partner accounts run every quarter, written as it actually happens. 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
Feedback from distributor and contractor accounts in three export regions.
- James Anderson (Government Project Tender Coordinator, Sydney, Australia): "We asked for the EN 54 test report before paying anything, and the file arrived the next morning with the notified body reference intact."
- Giulia Romano (Warehouse Operations Manager, Madrid, Spain): "Our landed cost per installed point dropped by roughly 23% after we moved from a trading office to direct factory supply."
- Thomas Eriksen (Construction Procurement Manager, New York, United States): "Spare bases and covers arrived in three weeks when a renovation crew damaged stock, which kept our New York 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.
