Why Do You Need a Buying Guide?
Die wireless level monitor market offers a wide variety of products with complex specifications, making it difficult for ordinary users to distinguish quality from inferiority. A systematic buying guide helps users avoid pitfalls and purchase products that truly meet their needs.
Below are key selection considerations organized across multiple dimensions, covering communication methods, sensor types, power solutions, protection ratings, and other critical factors.
Vraag 1: What is the Application Scenario?
This is the primary prerequisite for selection, directly determining the measurement principle and product material.
Faktore om te oorweeg:
- Medium Type: Clean water (fire water tanks, domestic water tanks) can use submersible or ultrasonic; sewage/corrosive media require anti-corrosion or non-contact types; media with大量 impurities/foam should prioritize ultrasonic or radar types
- Installasie -ligging: Indoor/outdoor, above ground/underground, accessibility
- Omgewingstoestande: Temperature range, Humiditeit, presence of corrosive gases
Recommendation: First clarify your application scenario, then filter suitable product types based on the scenario.
Vraag 2: Which Communication Method Should You Choose?
The communication method determines data transmission reliability, coverage range, en kragverbruik.
| Communication Method | Transmissieafstand | Kragverbruik | Penetration Capability | Suitable Scenarios |
|---|---|---|---|---|
| Lora | 3-5 km | Uiters laag | Uitstekend | Long distance, many obstacles, no power source |
| NB-IoT | Cellular coverage | Laag | Goed | Urban areas with cellular coverage |
| 4G | Cellular coverage | Hoog | Goed | High real-time requirements |
| Wifi | <100 m | Hoog | Swak | Indoor with WiFi coverage |
| Bluetooth | <30 m | Laag | Swak | Short distance, on-site viewing |
Recommendation: For water tanks in basements, Diep putte, afgeleë plekke, or sites without WiFi coverage, LoRa is the best choice. For wide-coverage scenarios like urban waterlogging monitoring, LoRa also has advantages.
Vraag 4: How to Choose the Power Solution?
The power method directly affects deployment flexibility and maintenance costs.
| Power Method | Voordele | Nadele | Suitable Scenarios |
|---|---|---|---|
| Battery (Lora) | Geen bedrading nie, flexible deployment | Requires periodic battery changes | Remote/elevated locations without power |
| Solar + Battery | Long-term maintenance-free | Hoër aanvanklike koste, needs sunlight | Long-term outdoor deployment |
| Mains Power | Continuous power | Requires wiring, fails during outages | Indoor with power available |
Recommendation: For water tanks, towers, Diep putte, and other locations without power access, choose low-power LoRa + battery power. HojellyTek's 8-month battery life significantly reduces battery change frequency.
Vraag 5: What Protection Rating is Needed?
The protection rating (IP code) indicates the degree of dust and water resistance.
- IP65: Dustproof + water jet resistant, suitable for outdoor non-submersion environments
- IP67: Dustproof + temporary submersion (1m for 30 minute)
- IP68: Dustproof + continuous submersion, suitable for underwater installation
Recommendation:
Underwater installation
Indoor dry environments: IP54 is sufficient
Outdoor rain exposure: At least IP65
Locations with possible submersion: IP67
