Discuss platform integration ↗ANSWERS FOR YOUR PROJECT
Frequently asked questions.
Practical answers for choosing a level range, matching liquid and vessel conditions, installing the probe and connecting readings to your operating workflow.
Ask about your project ↗What level range should I choose for my tank, well or sump?
Start with the highest level you need to measure, the probe reference point and the level tolerance required by your operation. The published H Series family covers 0–200 m with customization available. Select the actual full-scale range for the installation rather than using the widest range automatically. A tank drawing, well depth or sump section helps Hitelecom review the range, cable length and mounting together.
How does full-scale accuracy relate to my tank depth?
The published accuracy is ±0.5% FS, meaning a percentage of the selected full scale. As a calculation example, a 10 m full scale corresponds to ±50 mm at that stated percentage. Choose the range and any higher-precision option around the tolerance your task needs. The published ±0.2% FS/year stability describes change over time; temperature, liquid conditions and installation are reviewed separately when defining the complete measurement requirement.
What information helps match the sensor to our liquid?
Share the liquid composition and concentration, operating temperature, density behavior, suspended solids and cleaning conditions. These details allow the probe, seals and cable to be reviewed against the actual process. Water, effluent, oils and chemical solutions can need different configurations. Include the vessel pressure and required accuracy in the same brief so Hitelecom can define a suitable sensing arrangement and confirm compatibility for the supplied parts.
How can the probe cable and mounting be adapted to our site?
The published product supports customization of range, probe cable length and mounting. Specify the probe position, tank or well depth and route to the communication terminal, including service access and protection from mechanical loads. The terminal's mounting lugs, pole clamp or slotted mount depend on configuration. Agree how the submerged probe is positioned and supported separately, then document its level reference and cable route for commissioning.
How can we obtain stable readings in wastewater or a busy sump?
Choose a sensing position that represents the collection level and remains accessible for inspection. Review inlet turbulence, sediment accumulation, scaling and the liquid's chemical conditions with the probe selection. Suitable support or a protective arrangement can help maintain a consistent position, while an inspection plan keeps the sensing surface and cable in useful condition. Share the sump layout and expected solids so these details can be included in the installation proposal.
How do tank pressure conditions affect the measurement setup?
Tell Hitelecom whether the vessel is open, vented or pressurized. The H Series is published as a submersible level sensor; confirm the selected probe's measurement principle and pressure reference during configuration. For a pressure-based arrangement, an open or vented tank needs an appropriate atmospheric reference, while a sealed vessel requires the liquid-surface pressure to be considered. Review these details alongside the liquid density and level range.
Can level readings help estimate the volume stored in a tank?
Yes, when the tank geometry or a validated level-to-volume table is available. Level is a height reference; converting it to stored volume depends on the vessel shape and the chosen datum. Share the tank dimensions or calibration table, along with the required display units, so the calculation and receiving-platform implementation can be agreed. For irregular or horizontal tanks, use the appropriate conversion across the working level range.
Which wireless option fits our factory or remote water site?
Choose the connection around reception at the terminal, regional network support, reporting needs and the receiving platform. The published family lists 4G LTE, NB-IoT and LoRa options. For cellular projects, review the available operator coverage and selected modem configuration. For LoRa, include the gateway and server path in selection. Check the complete route from the installed terminal to the dashboard before completing site commissioning.
How can we connect level data to our own platform?
The published 4G and NB-IoT deployment sends level readings through MQTT to Hitelecom Cloud or a customer platform. Share the receiving endpoint, authentication approach, payload requirements and device identifiers so the integration can be agreed. Hitelecom Cloud also provides dashboards and configurable alarm rules. For a LoRa deployment or a project involving controllers, confirm the gateway, server and interface path as part of the supplied solution.
How should we balance reporting frequency and battery life?
Set the profile around how quickly the level changes and when the team needs to see it. The published battery reference is more than 10 years at four-hour reporting under specified test conditions. Actual runtime depends on the model, sensing and sampling demand, reporting frequency, temperature, signal coverage and retransmissions. Agree the required measurement and notification timing, then request a battery-life estimate for that configuration and site profile.
How can high and low alerts support refill and drainage operations?
Set high and low thresholds around the site's usable reserve, refill plan or collection capacity. Define the person who reviews each notification and the follow-up action, then verify the complete alert path during commissioning. For automated pump or valve operation, include the controller or PLC, suitable interfaces and operating logic in the project. The required response timing is agreed for the complete system, from level measurement through the selected control equipment.
What should we include in an application-specific quotation request?
Send the application, liquid specification, maximum level, vessel pressure and required tolerance, along with a site photo or drawing. Add the probe position, cable route, process and ambient temperatures, fouling conditions and inspection access. Include the wireless region, reporting profile, platform and any controller integration. Where the project needs contact approvals or hazardous-area documentation, identify the exact requirement so the proposed configuration and supporting evidence can be reviewed together.
