MEASUREMAN 4-1/2″ Water Level Gauge
The MEASUREMAN gauge indicates the depth of water in a well by utilizing air pressure to measure the water head. The device is mounted lower, with a 0-390 ft water head range. It operates by charging both the gauge and the air line to the well bottom; the pressure needed to release air determines the head of water above the end of the line. This setup supports deep wells and challenging hydrogeological conditions, offering robust performance in long-term monitoring applications.
Water Level Meter 10-300m with Fixed Probe
This electronic water level indicator uses a fixed probe and steel tape to measure water depth. It operates with a 9V battery housed in the reel hub; when the probe contacts water, the circuit closes, triggering a buzzer and a light. Readings are taken directly from the tape at the top of the well casing or borehole. It supports a wide range from 10 to 300 meters and features corrosion-resistant stainless steel components for durability in harsh environments.
Groundwater Level Gauge 98.4 Ft
This gauge offers two length options, including a 30 m (98.4 ft) variant, good for groundwater monitoring, dam safety inspections, and water management across varying environments. It provides 1 mm resolution with less than 2 mm repeatability error, ensuring consistent data for wells, boreholes, and reservoirs. A durable 0.99 inch stainless steel probe and waterproof contacts support long-term use in challenging water measurement tasks.
YJINGRUI 98ft/30m Water Level Meter
This meter uses a choice of probes depending on depth: a 25 mm diameter probe for 10-100 m ranges and a smaller 15 mm probe for 150-300 m. Both probes are 304 stainless steel, removable for cleaning. The device activates a light and buzzer when the probe contacts water, providing straightforward visualization and audible confirmation of the water surface level. It balances portability with reliable precision for field use.
328 Feet Water Level Meter with 0.98 Inch Probe
This meter provides a long span up to 328 feet (100 meters) with a 0.98 inch probe, designed for wells, boreholes, reservoirs, and pipes. It features an ergonomic reel with an audible signal, a readable centimeter scale (minimum reading 1 mm), and a robust stainless steel probe. The unit relies on a solid probe connected to a tape measure; it operates via a rechargeable 9V battery housed in the reel hub, offering dependable field readings and straightforward maintenance.
328 Ft Water Level Gauge 0.99 Inch Probe
This model also offers a 30 m and 100 m option, with a 0.99 inch stainless steel probe for durability and easy cleaning. Readings are taken from a steel tape, with a minimum resolution of 1 mm and a repeatability of 2 mm. A multi-feature reel includes a sensor-driven buzzer and a voltmeter signal, aiding quick interpretation in field operations. The device supports reliable measurements for boreholes, wells, and reservoirs with long-term use in varied climates.
98.4 Feet Water Level Meter with 0.98 Inch Probe
This model matches a practical length of 98.4 feet (30 meters) with a 0.98 inch probe, designed for ease of use and consistent readings. The ergonomic reel, buzzer, and battery test button support fieldwork efficiency. Readings are captured in centimeters with a stated 1 mm minimum increment and under 2 mm repeatability, making it suitable for routine groundwater monitoring and well testing in varied environments.
Buying Guide: Key Purchase Considerations
- Measurement range and depth: Choose a model that covers your well depth and anticipated groundwater head. Deeper wells may require gauges with longer ranges and robust air-line or tape mechanisms.
- Probe diameter and material: Stainless steel probes (typically 0.99 inch / 25 mm or 0.6-0.8 inch) resist corrosion and enable easier cleaning. Larger probes may be easier to thread and less prone to fouling.
- Readout method: Options include air-head pressure, electronic probes with buzzer and LED indicators, and voltmeter signals. Consider triggers like audible alarms for quick field interpretation.
- Durability and environment: Look for corrosion-resistant materials, weatherproof housings, and rugged reels if measurements occur in exposed or harsh conditions.
- Power and maintenance: Reels with built-in batteries (or battery compartments) should use readily available cells. Check for ease of probe replacement and reel maintenance.
- Accuracy and repeatability: Values such as 1 mm minimum reading and ≤2 mm repeatability are common; ensure the device meets your accuracy requirements for monitoring and reporting.
- Portability and ease of use: Lighter units with simple operation reduce fatigue during long measurement sessions and improve data consistency across operators.
- Application scope: Decide whether you need a single-well tool or a versatile meter suitable for wells, boreholes, reservoirs, and pipes.
- Maintenance and spare parts: Availability of replacement probes, tapes, and accessories can extend the life of the instrument in field conditions.
