Slowly open the valve and run enough water to 

dissipate entrained air and flush the line.

Check to make sure the meter is indicating flow.

Check the meter for leaks.

2.3 Complete Installation
After the meter has been installed:

Reset the transmitter. See “Send Reset Message” on 

page 2 for instructions.

Write down the odometer’s initial meter count for entry 

into the TapWatch 2 software.

Put the meter in rapid transmit mode. “Set Modes” on 

page 2 for instructions.

3.1 Remove the Power Pack
If it is necessary to remove the power pack:

Lift the outside edge of the battery pack enclosure away 

and up from the register to remove it.

Use a flat blade screwdriver to evenly lift the battery 

pack away from the register at the points marked 

L

IFT

 H

ERE

.

Remove the power pack carefully. If the pins are 

not kept perpendicular with the register during removal, 
they may break. Never remove the power pack by rocking it 
away from the register.

3.2 Rotate the Register
If the odometer is difficult to read, the register can be 
rotated.

The register should only be rotated if absolutely 

necessary. To rotate the register, you will need to purchase 
a new security pin from Inovonics Wireless. The security 
pin used in EN1550 is meant for one use only.

Use a punch to drive the security pin into the register 

(Fig. 1).

Turn the register 45 degress and lift it off of the meter.

Remove the broken security pin from the bottom of the 

register.

Replace the register in the desired position.

Use your thumb to insert a new security pin.

If you will need to rotate the register again, ensure 

there’s appropriate clearance to remove the security pin in 
the new position.

EN1550 Components

The flow indicator spins when water is 

flowing through the meter.

The odometer displays the number of gallons 

used, to the nearest 10 gallons.

The sweep hand indicates the single digit 

number of gallons that has passed through the meter. Each 
full revolution indicates 10 gallons of consumption, and 
will advance the first column on the odometer.
The meter in Figure 5 shows a consumption of 14.6 
gallons. The odomoter indicates that 10 gallons have been 
used, and the sweep hand adds 4.6 gallons to that 
number.

3.4 Send Reset Message
When the EN1550 is reset, the count is zeroed and an RF 
reset message is sent. The RF reset message is used for 
registration into TapWatch software. To reset the EN1550:

Push an unfolded paper clip through the guide hole to 

press and hold the Operation

 

button for five seconds 

(Figure 2).

3.5 Set Modes
In normal mode, the EN1550 transmits the flow count 
approximately once per hour, or upon every 100 gallons of 
water, whichever occurs first. When in rapid transmit 
mode, the EN1550 transmits the flow count approximately 
once per minute. Rapid transmit mode is used during 
installation, to help ensure all your programmed end-
devices are functioning correctly.
