a HYDRO+ based level monitoring system, are supplied with individual instructions.

All general start up information is included in the white pages. Refer to the grey pages

for additional information or technical assistance, if required.

ABOUT THE HYDRORANGER PLUS

The HydroRanger Plus is to be used only in the

manner outlined in the instruction manual.

The HYDRO+ includes the features of the successful Milltronics "HydroRanger 1"

PLUS a variety of new features, incorporating advances in electronic component,

manufacturing, and software technology.

This multi-purpose microprocessor based level monitor contains numerous features

ideally suited for liquid monitoring and pump control applications.

A HYDRO+ level monitor, utilizing a single ultrasonic transducer (ordered separately),

accurately monitors level without contacting the surface monitored.

The HYDRO+ provides the transmit pulse to the transducer. The transducer emits

ultrasonic pulses in a narrow beam, perpendicular from the transducer face. The

HYDRO+ measures the time between pulse emission and reflection (echo) reception,

to calculate the transducer face to monitored surface distance.

The transducer internal temperature sensor is used to automatically compensate

for sound velocity variations due to air temperature changes within the

measurement range.

The HYDRO+ monitors levels 0.3 to 15 m (1 to 50 ft) from the transducer face, with

outstanding accuracy, usually within 0.25% of range. (Ensure the transducer selected

suits the material and measurement range monitored).

This versatility is accomplished by Milltronics patented Sonic Intelligence TM, providing

high measurement reliability, regardless of operating conditions.

The HYDRO+ provides the following

LCD

(Liquid Crystal Display) Readings:

» Level, space, distance, volume, or remaining capacity in open or closed vessels.

» Differential level across a channel filter or screen (2 transducers required).

» Average level in a large vessel with an uneven material surface (2 transducers).

» Head, flow, or totalized flow in free flowing open channels.

» Pumped volume from wet wells or into reservoirs.

The HYDRO+ relays and/or mA output may be used as preset (or programmed as

desired) to activate alarms, pump controls, chart recorders, or virtually any process

control equipment.

The HYDRO+ infrared interface permits one programmer to be used for any number

of HYDRO+ level monitors. Upon programming completion, the programmer may be

locked away for programming security. All Operator programming is stored in

non-volatile memory, unaffected by power interruption.

While the HYDRO+ is typically used to monitor liquid level, any process which

requires a distance measurement or object presence/lack of presence (within the

system maximum measurement range) is a candidate for HYDRO+ application.

Refer to APPLICATIONS for detailed descriptions of a small sample of process

measurement requirements to which the HYDRO+ may be applied.

PROGRAMMABLE FEATURES

Typically, a very small percentage of the HYDRO+ operator programmable features

require alteration from default settings. However, for demanding measurement

requirements any number of features may be adjusted as required.

Following is a list of the features that make the HYDRO+ easy to program, yet

versatile enough to handle complex level measurement requirements.

GENERAL FEATURES

SCROLL ACCESS: Scroll forward or backward to key programmable features.

OPERATION: 7 modes of operation to suit specific requirements.

MATERIAL: Preset for optimum performance on all liquid surfaces.

RESPONSE: Slow, medium, or fast response to level changes.

UNITS: Readings in m, cm, mm, ft, in, %, (or any other units desired).

ADDITIONAL FEATURES (use as desired)

VOLUME: 8 pre-programmed tank shape options

2 universal tank shape programming methods

FLOW: Open channel flowrate and total, 5 pre-programmed flumes.

PUMPED TOTAL: Total volume pumped including/excluding inflow/discharge.

DATA LOGS: Time and Date of important operational events.

FAIL-SAFE: Automatic process control equipment activation.

RELAYS: 6 alarm functions, 7 pump functions, 5 control functions,

storm condition and energy saving pump function modifiers.

mA OUTPUT: 7 functions, range selectable and scalable, overrange limits.

mA INPUT: HYDRO+ features based on any level monitor mA output.

PL-507 8

INSTALLATION

Installation shall only be performed by qualified personnel,

and in accordance with local governing regulations.

ENVIRONMENTAL

Choose a mounting location suited to the HYDRO+ enclosure.

The ideal HYDRO+ mounting location is where the:

1. Ambient temperature is always within -20 to 50°C (-5 to 122°F).

2. HYDRO+ display window is at eye level.

3. Cable length requirements are minimal.

4. Mounting surface is free from vibration.

Avoid mounting locations where the HYDRO+ is:

» exposed to direct sunlight, (otherwise, provide a sun shield).

» close to high voltage/current runs, contactors, SCR control drives, or

frequency inverters.

This product is susceptible to electrostatic shock.

Follow proper grounding procedures.
