HYDRANT DRAIN METER

Hydrant Drain Meter HYD-10 is used to detect draining levels of hydrants in order to 

prevent them from freezing in winter months.  Hydrants in areas where temperatures 

are consistently below freezing,  have a higher tendency to freeze.  These hydrants are 

dry barrel type, where the water should not remain in the barrel after use.  Hydrants 

that have water in the barrels after use need to be pumped out to avoid freezing in 

the winter.  The reasons for water remaining in the barrel could be, a leaking main 

valve,  clogged drain plugs or high-water table.  Monitoring these hydrants with the 

Hydrant Drain Meter HYD-10,  allows cities and municipalities to avoid safety issues 

of non-functioning hydrants due to freezing.

The Hydrant Drain Meter HYD-10 can measure the depth of water in the hydrants 

barrel if any. The meter comprises of a metal probe fitted to a flexible twisted 

color-coded cable which is wound on to a portable hand reel containing an 

electronic switched circuit, visual indicators and batteries.

The Hydrant Drain Meter is simple to use and is portable which allows it to be used 

easily at many locations.  The twisted color-coded cable allows the probe to be easily 

dropped inside the hydrants port cap and removed without any resistance.  The 

Color-coded wires allow the user to quickly identify the depth without needed to 

reference the foot measurements.

The Hydrant Drain Meter HYD-10 has a 10 foot measuring depth and comes with 

pre-installed (2) 9 Volt batteries and a carry bag.

- Flexible cable for easy winding and unwinding, even in 

        cold temperatures

- Waterproof design

- Color coded wire fast depth measurements 

- Strong 80lb base magnet allows it be placed at any angle 

         and location on hydrant

- 3 bright LED signals, that can be view at any angle even 

         in bright sunlight up to 20 ft

- (2) 9 volt batteries power the tool providing maximum 

         usage between battery changes

- Can identify water drainage rate by simple calculation

- Ergonomically designed for ease of use

- Probe can quickly and easily be attached to magnetic while 

        not in use or can hang from handle prior to use 

- Magnetic base allows it to be fastened on metal panel of 

        work van or any metal surface for quick and easy access

- Identifies hydrants that are not fully drained and need to 

        be pumped out to prevent freezing in winter months 

- On/ Off switch conserves battery life

The Hydrant Drain Meter is used to measure the standing water level inside a 

dry barrel hydrant.  The Hydrant Drain Meter can be used at any angle and can 

be easily attached to any hydrant using the magnetic base.

Each Hydrant Drain meter is comprised of a metal probe fitted to a flexible cable wire 

that is wound on to a hand-held reel with an ergonomical handle.  The cable is 

connected to an electronic circuit, 3 LED (light) signal indicator and (2) 9 volt 

batteries and an On / Off switch.

The sensor probe incorporates an insulated gap which acts as a switch, the circuit 

being completed when contact is made with the water.

The cable consists of a non-stretch twisted color-coded wire with copper 

conductors, also marked in one foot intervals.

The Probe is lowered down the port of a hydrants barrel to be tested.  When 

it makes contact with water,  the 3 LED’s come on,  located at the top of the tool. 

A reading can then be taken from the measuring cable at the port level to 

record the depth. 

The probe can also be left in the barrel at the desired drain depth.  When 

draining to this depth is complete, the LED’s will turn off which indicates 

that no water is left standing at this level of the barrel. 

Drain test after Hydrant use:

- Turn on unit, by pressing in button

- Place sensor probe through hydrant port and lower do desired drain 

         depth as required

- Use color code of wire to quickly identify depth to leave sensor

- Once water level is drained at this level,  the LED lights turn off

- Unit can be turned off when drain test is complete, by depressing button

Drain test Before Hydrant use/ Check for Frozen hydrant:

- Turn on unit, by press button

- Place sensor probe through Hydrant port and lower slowly 

-      Lights will turn on when water is detected (hydrant was not fully drained)

- Note the Depth by the color-coded wire 

- If hydrant frozen - depth can be identified (LED lights will not turn on if frozen)

- Unit can be turned off when drain test is complete, by depressing button

Measuring the depth to the closest ½”

- Use the cap‘s ½” notched  lines as a guide 

- Place the  wire along rubber sides and count notches 

- Example:  2 notches equal 1”  - 6 notch’s equal 3”

- Also, the distance between LED’s along rubber sides is 4” (8 notches)

No Signal when unit is turned on and probe is in water.

- The battery is discharged. Check the battery. 

          (Section 5: Battery Replacement)

- The circuit is malfunctioning.  Contact H2O Tools.

No Indication of water.

- The conductive probe contacts are dirty,  clean the contact. 

        (section 5: Cleaning the conductive contact)

- There is an open connection in the cable.  Replace the cable 

         and or the probe.

- The circuit is malfunctioning.  Contact H2O Tool.s

The signal LED’s are intermittent.

- There is an open connection in the cable.  Replace the cable 

         or probe.

- There is a loose connection in the circuit or the probe. 

           Repair the connection.

The signal LED’s are continuously. 

- The Conductive contact is dirty (causing bridging). 

         Clean the contacts. (section 5: Cleaning the conductive contact)

- There is a short in the cable or probe.  Replace the cable or probe.

- The circuit is malfunctioning.  Contact H2O Tools.

The signal LED’s stay dim after probe is withdrawn from water.

- When using the unit in areas of hard water, the LED’s may 

        continue to respond after the probe is withdrawn from the 

        water.   When this happens, the LED’s will stay on faintly 

        and not on full brightness.  Dry out the probe contacts or 

        blow out the electrode.
