Moray ME6001W Wireless Tank Level Monitoring System Instruction Manual

1. Introduction

The Moray ME6001W is a state-of-the-art wireless liquid level transmitter designed for intelligent water tank monitoring and various industrial applications. This device features low power consumption and robust wireless communication capabilities, supporting multiple network types including WiFi, 4G, LoRaWAN, Zigbee, and NB-IoT. It provides accurate and efficient data acquisition and analysis through PC or mobile terminals, enabling remote monitoring and comprehensive alarm reporting for critical environments.

2. Setup Instructions

2.1 Physical Installation

The ME6001W features an explosion-proof shell design, constructed from cast aluminum and stainless steel 304, ensuring durability and safety in harsh environments. The sensor incorporates an imported diffusion silicon core for high precision measurements.

Mount the transmitter securely using appropriate hardware for your application. Ensure the submersible sensor is placed correctly within the liquid to be monitored. The device is designed for various applications including fire water tanks, natural gas pipelines, water/wastewater systems, and oil/petroleum/diesel tanks.

2.2 Power Supply

The ME6001W is powered by an integrated 3.6V@38Ah Lithium Battery. To install or replace the battery:

1. Carefully unscrew the top cover of the transmitter to access the battery compartment.
2. Insert the 3.6V@38Ah Lithium Battery, ensuring correct polarity.
3. Securely re-attach the top cover, ensuring a tight seal to maintain the IP66 ingress protection rating.

2.3 Network Configuration

The device supports multiple network types. If using 4G or NB-IoT, insert the appropriate SIM card into the designated slot (refer to Figure 5 for SIM slot location). The transmitter communicates using MQTT/HTTP/TCP protocols.

3. Operating Instructions

3.1 Initial Power On

Locate the ON/OFF switch inside the transmitter (visible after removing the top cover, as shown in Figure 4) and switch it to the 'ON' position. The OLED display header will illuminate and show current readings.

3.2 Data Monitoring

Monitor data via PC or mobile terminals using the Moray Data Platform or your self-built platform. The system provides real-time data refreshed online, and historical data can be stored and downloaded for analysis.

3.3 Remote Settings and Alarm Reporting

The system allows for remote configuration of various parameters:

• Data Collection & Transfer Frequency: Adjust how often the device collects and sends data.
• Alarm Limits: Set thresholds for liquid levels or pressure fluctuations. The system will automatically report abnormal conditions, including low battery levels and over-threshold events.
• Remote Configuration: All settings can be managed remotely via the monitoring platform.

The device also supports OTA (Over-The-Air) remote upgrade sampling for firmware updates and parameter adjustments.

4. Maintenance

4.1 Battery Replacement

The ME6001W's low power consumption design provides a battery life of over 3 years with a 10-minute sending interval, and over 5 years with a 1-hour sending interval. When a low battery alarm is triggered, replace the battery promptly:

1. Power off the device by switching the ON/OFF switch to 'OFF'.
2. Carefully unscrew the top cover of the transmitter.
3. Remove the old 3.6V@38Ah Lithium Battery and insert a new one, ensuring correct polarity.
4. Securely re-attach the top cover, ensuring the seal is intact to maintain environmental protection.

4.2 Sensor Cleaning

Periodically inspect the submersible sensor probe for any buildup, debris, or fouling that might affect measurement accuracy. Gently clean the probe with a soft cloth and an appropriate cleaning solution suitable for the measured liquid, taking care not to damage the imported diffusion silicon core.

4.3 Firmware Updates

The device supports OTA remote upgrade sampling. Ensure your device has a stable network connection to receive and apply any available firmware updates. Regular updates ensure optimal performance, security, and access to new features.

5. Troubleshooting

5.1 No Display/Power

• Check ON/OFF Switch: Ensure the internal ON/OFF switch is in the 'ON' position.
• Verify Battery: Check the battery charge level. If low, replace the 3.6V@38Ah Lithium Battery.

5.2 No Network Connection

• SIM Card (if applicable): Ensure the SIM card is correctly inserted and active with a valid data plan.
• Network Signal: Check the network signal strength in the installation area. Relocate the device or use an external antenna if the signal is weak.
• Network Configuration: Verify that the device's network settings (e.g., APN for 4G/NB-IoT) are correctly configured on the monitoring platform.

5.3 Inaccurate Readings

• Sensor Inspection: Inspect the submersible sensor probe for any physical damage, obstructions, or excessive buildup. Clean if necessary.
• Correct Placement: Ensure the sensor is correctly submerged and positioned according to the liquid level measurement requirements.
• Environmental Factors: Consider if extreme temperatures, liquid turbulence, or other environmental factors might be affecting the measurement.

5.4 Alarms Not Triggering

• Alarm Thresholds: Verify that alarm thresholds are correctly set on the monitoring platform.
• Network Connectivity: Ensure the device has a stable network connection to send alarm reports to the platform.
• Platform Notifications: Check your monitoring platform's notification settings to ensure alarms are configured to be received.
