Page 5: Bubbler Features
Introduction The WaterLOG® H-3553T/ Pressure Sensor is well known for its compact size and combination of a Bubbler and built-in pressure sensor. The H-3553T has also been referred to as a self-contained “smart” gas purge system, because it produces a precision constant mass flow of gas. Designed to measure fluid levels in surface water, ground water and tanks, the H-3553T Modbus or Auto mode is enabled it will enter the RS-232 menu with any character sent to this port. -

Installation The WaterLOG® H-3553T is a system with a fully integrated digital pressure transducer specifically designed for water level monitoring. The H-3553T directly measures dry gas over a broad temperature range. WARNING! Before proceeding with the installation, please consider the following site preparation steps to help prevent problems later. -

Page 14: Rs-232 Menu
SETUP & OPERATION There are three ways to setup and operate the H-3553T, through the RS-232 menu interface, the SDI-12 interface, and through the XL series DCP menu interface. Setup through the XL series DCP menu is not discussed in this manual but is discussed in the XL series manual. This chapter will focus on setup using the RS-232 menu interface and the SDI-12 interface. - Page 15 Setup & Operation SDI-12 Interface The SDI-12 interface is another way to setup and operate the H-3553T. The H-3553T supports all standard SDI-12 commands and uses some SDI-12 extended (manufacturer specific) commands for setup operation. SDI-12 standard and extended commands are normally sent from a SDI-12 master device, like the Waterlog XL series DCP.

SETUP & OPERATION Default Setup The H-3553T has many settings that can be change. However, the default setups will normally cover most applications. Table 4-3 shows the default settings for the H-3553T. Table 4-3: H-3553T Default Setup Setting Default Setting Setting Range SDI-12 Address 0-9 (Standard), A-Z, a-z... -
Page 17: Sdi-12
Setup & Operation SDI-12 The SDI-12 address of a sensor is its identifier on the SDI-12 data bus. The SDI-12 data bus is a one wire communication between normally one master device and one or more slave devices. The SDI-12 address makes it possible for the master device to communicate with each sensor individually. -
Page 18: Set Current Stage
SETUP & OPERATION Note Table 4-7, the ‘a’ is the current SDI-12 address of the H-3553T and the ‘xxxx’/’x.xxx’ is the current units/ slope of the H-3553T and the ‘nnnn’/’n.nnn’ is the desired new units/slope.

Page 19: Stage Offset
Setup & Operation Stage Offset The stage offset is a value that is added to the final stage result after the slope/multiplier has been applied. The stage offset is normally used to obtain a final stage level relative to some reference point such as sea level. Writing the stage offset is not needed when using the set current stage option, because this option calculates and sets the stage offset automatically. -

SETUP & OPERATION Note: This averaging time does not take into account the time it takes to make an atmospheric reading. Therefore, always add about 4 more seconds to the averaging time to calculate how long the full measurement cycle can take.

Page 22: Purge
SETUP & OPERATION Purge The H-3553T has an option built in called purge, the purpose of the purge is to clear out any debris or silt from the end of the orifice line that could cause false pressure readings. When a purge is initiated the H-3553T makes a new measurement on the line and tank sensor and saves the values away just in case data is requested during the purge. -

Page 26: Modbus Mode Enable
SETUP & OPERATION Modbus Mode Enable The Modbus mode enable is the setting that determines whether the H-3553T will communicate with a Modbus master device. Modbus is an industry standard serial digital interface for interconnecting Programmable Logic Controllers (PLCs), intelligent sensors and other devices. The H-3553T can be used as a Modbus slave and has a serial RS-485 port for connecting to a Modbus compatible host device. -
