Flow-sensor configuration for 6-20L tankless gas water heaters

This page is for buyers evaluating a tankless LPG or natural-gas water heater with a water-flow-sensor configuration. The flow-sensor selection must match the intended heater capacity, activation conditions, valve arrangement and control system. Confirm the exact sensor configuration before sampling or bulk production.

What to confirm for a flow-sensor configuration

Required hot-water supply: 6L, 7L, 8L, 10L, 12L, 14L, 16L or 20L.
Destination gas type: LPG or natural gas.
Specified operating water-pressure range: 0.02-0.8MPa.
Required activation-flow behaviour for the intended installation.
Sensor connector, control-board and valve compatibility for the selected configuration.
Whether a replacement-sensor and spare-parts plan is required for after-sales service.

Why water flow must be evaluated with the full installation

Water-flow behaviour is affected by more than one component. Inlet filters, pipe size, valves, inlet pressure, water quality and the selected heater configuration can all affect operation. For this reason, a sample should be checked using the target gas type and the intended installation conditions before confirming a production configuration.

Series capacity reference

Hot-water supply	Rated heat load	Product size (mm)
6L	12KW	440 × 300 × 120
7L	14KW	500 × 300 × 155
8L	16KW	520 × 320 × 155
10L	20KW	590 × 340 × 180
12L	24KW	620 × 340 × 180
14L	28KW	650 × 395 × 188
16L	32KW	650 × 395 × 188
20L	40KW	700 × 440 × 188

Flow-sensor RFQ checklist

Provide the target capacity, gas type, operating water-pressure conditions, intended installation, connector/control-system requirements, expected volume and sample-test requirement. This information allows the factory to review the suitable configuration rather than treating “flow sensor” as a generic product claim.

Flow-sensor product FAQ

Is a flow sensor by itself enough to solve low-flow complaints? No. Installation water pressure, filters, pipework, valves and the full heater configuration also need review.

Can a replacement-sensor strategy be included in an OEM order? Confirm the selected configuration and required spare-parts scope when requesting a quotation.

Water-flow sensor selection for tankless gas heaters

A flow sensor can affect when the heater detects demand and begins its heating sequence. Low-flow complaints are not always caused by the sensor alone; filters, scale, inlet pressure, valves, pipe size, and gas supply can also affect the result.

Useful RFQ information

Minimum activation flow and normal operating flow
Water pressure range and water-quality conditions
LPG or natural gas and target capacity
Sensor connector, control board, and replacement strategy
Expected annual volume and sample test plan

We can review the application and recommend a compatible configuration for OEM or distributor sourcing. Final commissioning should be completed by a qualified local technician.
