How To Read An Encoder
The HR-E LCD encoder has a 9-digit Liquid Crystal Display (LCD) to show consumption, flow and alarm information. The display automatically toggles between 9-digit and 6-digit consumption, rate of flow and meter model.
Alcoholic Beverage Fusel Alcohol Testing With Static Headspace
A static headspace method was developed using Teledyne Tekmar automated headspace vial samplers to meet the method requirements of the Alcohol and Tobacco Tax and Trade Bureau of the US Department of the Treasury (TTB) method SSD: TM:2001 for testing fusel alcohols in alcoholic beverages.
Application Note: Employing Best Water Quality Monitoring Practices To Reduce Runoff During Construction
Under proposed EPA stormwater runoff guidelines, construction site operators will be required to actively monitor or sample stormwater discharges daily. The enhanced effluent rules take effect in August 2011 for construction sites that disturb 20 or more acres and February 2014 for sites that disturb 10 or more acres, and they may stipulate a strict numerical limit of less than 280 NTU for average turbidity (sediment in water) on any day.

The Basics: Testing RO Quality
Osmosis is the phenomenon of lower dissolved solids in water passing through a semi-permeable membrane into higher dissolved solids water until a near equilibrium is reached.
Hydrant Pressure Monitoring Application Note
The simplicity of the compact, battery-powered Telog HPR-31 enables you to put it to work within minutes of unpacking. Once installed, the Telog HPR-31 measures water pressure at user programmable rates up to four samples per second with its internal pressure transducer. You can determine how often such data is summarized for reporting. The recorder computes any combination of minimum, average and maximum pressure measurement at each interval according to your selection of statistics and recording intervals. Recorded data may be gathered via an RS-232 connector using a handheld device or a laptop.
Application Note: Busseron Creek Watershed Partnership Addresses Concerns In A Rural Watershed
As with other watershed organizations, the
Busseron Creek Watershed Partnership
(BCWP) exists because of surface water
quality degradation. In this case, those
waters drain 163,231 acres of a watershed
that crosses the boundaries of Vigo, Clay,
Green, and Sullivan counties in West-
Central Indiana. By YSI
Application Note: Troubleshooting A pH Electrode
Many factors affect performance of a pH electrode. When performance degrades, it is always a challenge for the analyst to identify the cause. Common troubleshooting procedures, which include evaluation of slope, electrode drift, time response, and accuracy, take considerable time. By Thermo Fisher Scientific
Thermal Flow Meters For Mixed Gas Applications
Fox Thermal Flow Meters use a constant temperature differential (constant Δ T) technology to measure mass flow rate of air and gases.
Ultrasonic Level Measurement In Water And Wastewater Plants
Radar technology is often viewed as the “best” method of level measurement, but this isn’t necessarily true in the water industry.
Application Note: YSI Real-Time Water Quality Monitoring And The IPSWATCH-EMPACT Program
The Ipswich and Parker Rivers watersheds lie only a short
distance north of Boston, MA. The first settlements in these
watersheds began in the early 1600s. Since that time, residents
have relied heavily on the natural resources of the Parker and
Ipswich Rivers, their coastal estuaries and Plum Island Sound,
which is known as the Great Marsh. This ecosystem has been
designated and protected by the Commonwealth of Massachusetts
as an Area of Critical Environmental Concern (ACEC).
