Tank Level Indicator Buying Guide: 7 Key Questions to Make the Right Choice
Target Audience: Procurement Managers, Engineering Technicians, Home Users
Introduction
The tank level indicator market offers a wide variety of products with complex specifications. How do you choose the right product? This article starts from 7 key questions to help users make informed purchasing decisions.
Question 1: What is the measured media?
This is the primary prerequisite for selection. Different media have significantly different requirements for sensors:
| Media Type | Recommended Sensor | Reason |
|---|---|---|
| Clean water/drinking water | Ultrasonic/Submersible | Both work, ultrasonic better for maintenance-free |
| Sewage/wastewater | Ultrasonic | Non-contact, no scaling |
| Diesel/gasoline | Ultrasonic | Non-contact, safe |
| Chemicals/acids/alkalis | Ultrasonic (anti-corrosion) | Non-contact, corrosion-resistant |
| Viscous liquids/slurries | Ultrasonic | Non-contact, no adhesion |
| Solid particles/powders | Radar/Ultrasonic | Non-contact, dust-resistant |
Industry selection guides clearly state: For media containing impurities, foam, or corrosive substances, non-contact ultrasonic sensors should be prioritized.
Question 2: What accuracy is needed?
- Rough indication: Mechanical float gauge is sufficient, lowest cost
- Precise monitoring: Ultrasonic level meter, accuracy up to ±0.5% FS
- Process control: Requires high-precision sensor + data logging
HojellyTek ultrasonic solution provides precise level percentage readings, meeting most monitoring needs.
Question 3: Where is the installation location?
- Indoor/with power: Mains power solution works
- Rooftop/outdoor: Requires waterproofing (IP65+), solar power recommended
- Remote/no power: Must have solar + battery solution
- Deep well/underground: Requires IP68 protection
HojellyTek solar + battery solution perfectly adapts to outdoor no-power scenarios-2.
Question 4: Is remote monitoring needed?
- Local viewing only: Mechanical or local-display electronic is fine
- Remote viewing required: Must choose smart device with WiFi/LoRa/4G
- Mobile App needed: Confirm device supports Tuya/Smart Life mainstream platforms
HojellyTek supports both local LCD display and Tuya App remote monitoring – meeting dual needs.
Question 5: Is alert functionality needed?
- No alerts needed: Basic indication function is sufficient
- Alerts needed: Confirm device supports high/low level alert push
- Multi-channel alerts: App push + SMS + email more reliable
HojellyTek supports multi-channel alerts via Tuya platform, ensuring critical information is not missed.
Question 6: How to choose power supply?
| Power Solution | Advantages | Disadvantages | Suitable Scenarios |
|---|---|---|---|
| No power needed | Lowest cost | Limited functionality | Mechanical indicators |
| Pure battery | Flexible deployment | Requires periodic changes | Short-term/temporary use |
| Mains power | Continuous power | Needs wiring, fails during outages | Indoor with power |
| Solar + battery | No wiring, long-term maintenance-free | Slightly higher initial cost | Rooftop, outdoor, remote |
Industry selection guides point out that solar or battery-powered sensors are suitable for sites without power supply-2.
Question 7: What is Total Cost of Ownership (TCO)?
| Cost Item | Mechanical | Sight Glass | Submersible + Transmitter | Pure Battery Ultrasonic | HojellyTek |
|---|---|---|---|---|---|
| Device cost | Very low | Low | High | Medium | Medium |
| Installation cost | Low | Medium | High | Medium | Low |
| Annual maintenance | Medium | High | High | Medium-High | Very low |
| 3-Year TCO | Medium | Medium-High | High | Medium-High | Lowest |
Quick Decision Matrix
| Requirement | Recommended Solution |
|---|---|
| Lowest cost, rough indication | Mechanical float gauge |
| Precise reading needed | HojellyTek ultrasonic |
| Remote viewing needed | HojellyTek (Tuya App) |
| Alert functionality needed | HojellyTek (multi-channel) |
| Rooftop/outdoor no power | HojellyTek (solar + battery) |
| Sewage/corrosive media | HojellyTek (ultrasonic non-contact) |
