Meter Sensing Instruments

The AquaCalc 5000 is an electronic streamflow measurement and data logging device designed for use with USGS Price-type current meters. The hand held AquaCalc 5000 contains algorithms for both Type AA and Pygmy current meters, thereby displaying the velocity at each subsection. Total streamflow can be displayed by simply pushing a button. This replaces the headphone, stopwatch, rating table and notepad for a much more efficient way to make discharge measurements. The AQ 5000 was designed to be used with the standard Type AA, Type AA-MH or Pygmy current meter and requires no modifications to the meters. This allows maximum versatility so that the same meter can be used with either headphones or the AQ 5000. It can also be used with both wading rod or cable suspension by sounding reel. This unit does so much more than just a digital velocity indicator. It not only displays velocity but at each subsection either 0.2, 0.6, 0.8 measurements can be entered as well as the distance between each station. Then, at the end of the measurement a single button "Calculate Discharge" is pushed and the total flow in CFS or CMS is displayed. During the measurement the display continuously shows velocity, time, and revolutions so the measurement can be observed during the full 40 second averaging period or this time can be programmed for any non-standard time. Other features include programmability for non-standard meters (horizontal axis propeller meters), angle correction, surging flow compensation and automatic power off. At the end of the day or in the field with a laptop PC the data collected can be downloaded by RS-232 cable and software CD (both provided) to your office computer for data analysis and report printing. Data can be printed out in standard USGS discharge measurement format. When the AquaCalc is attached to a top-set wading rod with the optional rod mount and adapter, stream measurement becomes a one-handed operation.

AquaCount - Model 5100 Price-Type Current Meter Digitizer

The AquaCount provides a digital readout for Price-type AA and Pygmy current meters. It eliminates use of the headphone and stopwatch while it is a simplified version of the AquaCalc 5000 flow computer. The AquaCount not only counts the revolutions, calculates and displays velocity in feet per second or meters per second, but time, revolutions and velocity are all simultaneously displayed on the LCD display. The AquaCount can be used with no modification or retro-fit of a standard Price-type current meter. Just plug it into the same connector you have for your headphone and immediately start reading velocity, revolutions and time. The AquaCount can be used with wading rods or cable suspended systems. It uses the same advanced CMOS circuitry as the AquaCalc 5000 which has proven itself in the USGS to be the accepted standard.

Features:
Directly compatible with any existing Price-type current meter. No retrofit or modification required.
Advanced CMOS circuitry with crystal based timing for accu- rate and reliable measurements.
Display simultaneously shows velocity, revolutions and time. No need to wait until the end of a measurement cycle.
Easy to read 32 character LCD display reading 4 significant figures.
Uses a single 9 V battery with power conserving standby circuitry for long battery life.
Sealed membrane buttons and water resistant sealed circuitry.

Physical Characteristics:
Size:7" x 4" x 1" (18 cm x 10 cm x 3 cm)
Weight:1 lb. (.4 kg)
Velocity Range: 0 to 25 ft/sec. (0 to 7.6 m/sec.)
Temperature Range:- 20 degrees C to + 70 degrees C
Display Resolution: 0.001

Rod Mount - Model 5014

The Rod Mount allows your AquaCalc to be mounted to the top-set rod, leaving one hand free. With a Rod Mount, your AquaCalc can pivot up and down for the optimum viewing angle. 

TOP

Rod Adaptor - Model 2114

This aluminum bracket, used with a Rod Mount, allows your AquaCalc to be mounted on the top of the top-set rod just above the handle. This places the AquaCalc in an optimal viewing position.

The AquaCalc Pro is the natural successor to the AquaCalc 5000, with added features, such as a waterproof enclosure, a 3-year warranty, a large graphical display, an audible tone and the capability to perform discharge measurements using the majority of the current meters available around the world. USGS input and the user comments over the past 10 years have been incorporated into the AquaCalc Pro. Thanks to input from the field, the AquaCalc Pro is more versatile and user friendly than the AquaCalc 5000. The Pro has the ability to run in multiple modes including a simplified mode similar to the Basic series firmware and a professional mode similar to the Advanced series firmware available in the AquaCalc 5000. This additional versatility will allow the user to customize the AquaCalc Pro from the most basic operating mode with on-screen prompts and warnings that step you through a measurement to a more streamlined mode. The AquaCalc Pro provides one-key quick access to the measurement screen where you will see up to five vertical observations at a time on one screen. When you have completed your discharge measurement, you can download it to your computer and directly evaluate it or print it out for evaluation and filing.

The headphone converts into sound the electrical impulses caused when the circuit is completed in the contact chamber of the current meter. The headphone consists of a single earphone with a headband and a soft, plastic-covered rubber ear cushion. The system is powered by an AA 1.5-volt battery. A 4 foot (1.2 meter) long, two-wire electrical cord leads from the headphone battery case to a standard connector.

This headphone has two earphones with a soft, plastic-covered rubber ear cushion. The headphone uses a N-type (1.5 volt) battery which is located in the earpiece. It is also offered with volume control so that the hydrographer can increase the volume when encountering loud background noise during a measurement.

AquaPulse - Impulse Counter-Timer - Model 5020

The AquaPulse is an updated LCD impulse counter with timer display which registers the number of revolutions made by the bucket wheel of a current meter. The counter eliminates the need to count every revolution during a velocity observation. The timer display also eliminates using a stopwatch and allows both bucket wheel counts and time to be read easily and quickly. The time is selectable from 10 to 100 seconds

USGS Stopwatch - Model 5060

A stopwatch is necessary for use with the headphone, beeper, and Impulse counters to determine the number of bucket wheel revolutions in a given length of time. A high-quality stopwatch used by the USGS can be supplied by our company. It is a seven-jewel, split-second, non-magnetic watch with a 30 minute counter. The case is rust and water resistant with a dust-proof and shockproof mechanism.   

USGS Stopwatch Holder and Strap
This is the standard USGS leather holder and strap which enables the user to wear the stopwatch on his wrist. 

Digital Stopwatch - Model 5065

The Digital Quartz Stopwatch is an electronic stopwatch reading to 1/100 of a second. Furnished with a neck cord and having easy to use fingertip control buttons, it comes in a water- resistant case. Under steady and repeated usage, battery life of this stopwatch should be two years or more.  

Pocket Beeper - Model 5070

The beeper is another alternative for recording the revolutions of a bucket wheel. It consists of a small box containing a sound amplifier, a speaker and 9 V battery. A tuning knob near the top of the beeper case is used to tune the signal. A two-wire electrical cord with a standard connector socket (like the headphone and counter) is used to connect this unit to the meter.
