Understanding the Difference Between Orange Research Piston and Diaphragm Sensors
Orange Research is well known for their rugged and reliable differential pressure gauges, flow meters, switches and transmitters. They provide differential pressure measurement instruments that commonly use two different sensors to indicate the pressure difference across two ports, piston and diaphragm sensors.
Piston DP instruments are commonly used for liquid applications that will tolerate a slight amount of media bypass.
Diaphragm DP units, commonly used in air, gas and liquid applications, isolate the high and low pressure ports, eliminating and eliminate media bypass.
Understanding the specifics of your application will determine which design is better suited and consultation with an applications expert is strongly recommended.

Simplified SSO and CSO Event Recording with Volume Lost and Datalogging
 |
| Sanitary sewer overflows cause environmental damage. |
Urban development generates an increased volume and frequency of sanitary sewer overflow and damages the environment by allowing the propagation of contaminants and pathogens. To correct these problems, we must first understand the magnitude of these events in order to provide the proper resource is depending on the severity of each situation.

| FlowMade |
Maid Labs, a manufacturer of innovative and high quality flow meter products, has instrumentation that simplifies the measurement and recording of CSO or SSO volume loss. These Maid Labs products offer treatment facilities extremely simple operation and data logging. Precious time is not wasted learning complex software, converting data or creating reports.
The Maid Labs FlowMaid level monitor, open channel flowmeter and data logger generates the
required reports directly on the USB drive in and Excel compatible format. The FlowMade records the CSO or SSO volume loss into reports using one of the many industry standard full algorithms incorporated by Maid Labs engineers.

The FlowMaid is a small monitoring device used to record level, flow, volume and discrete events. It calculates the volume lost in a SSO event using the Manning equation. As an open channel flow meter, the user can select from 11 flow formulas. The only requirement is to enter the level of the overflow pipe, its diameter, material and angle. Years of data can be recorded before filling its memory. Every event shows start and end time, duration, average flow and volume lost.

Fuji Electric’s Spool Piece Ultrasonic Flowmeter (FST)
Flow rate inside a pipe is not uniform. A way to correct for this phenomena so that measurement can be accurately obtained is with the use of multiple internal flow sensors.
By using three sets of sensors, at three parallel paths to each other, the Fuji Electric FST flowmeter can sense both the flow rate at the center of the pipe and the flow rate near the pipe wall. Advanced electronics in the flowmeter housing then averages the flow rates based on Fuji's algorithm to achieve the accuracy of ±0.2% of rate. The Fuji FST delivers accurate measurement regardless of the point of measurement, without being affected by the change in the flow velocity profile.
APPLICATIONS
============
Reduction of water used in plant utilities - Visual depiction of a facility’s water use results in more effective management of water consumption.
Flow monitoring in filtration equipment - Real-time visualization of the filtration capacity allows for the optimization of flow rates, while reductions in pressure loss result in energy savings.
Motor load reduction - Reductions in power consumption are achieved by using an inverter only, instead of a combination of motorized valve and controller to control flow rate.
Flow measurement on two pipes - Optimal ratio of flow control for both pipes.
Liquid level control in tanks - Monitoring the flow rate at inlet and at outlet enables you to manage the liquid level in a tank.

Common Uses of Differential Pressure Gauges in Industrial Applications
Pressure Drop Across Filters, Heat Exchangers, Condensers, Evaporators, Pumps and Valves

Monitoring pressure drop – wherever it occurs – can offer incremental opportunities for improving process conditions and savings. Pumps and compressors move liquid or air within each process at a high cost, sometimes being driven harder than required. Reducing pressure lost within each process component may reduce the need for larger, more expensive pumps and compressors, and generally create more efficient flow and a better end product.
Flow Measurement

Flow is another common application for differential pressure gauges. There are countless types of flow meters in use today. The number one method for measuring flow is differential pressure flow monitoring. DP flow meters are especially attractive options for larger pipes. The cost of many flow meters goes up exponentially as the pipe size grows, because the scale of the flow element must increase to handle such large flows.
The popular solution is to cut the pipe, install an orifice plate and measure the pressure drop across the orifice plate. A DP flow meter is designed to handle the square root relationship between the flow and the differential pressure created, using Bernoulli's Law. This represents a high accuracy solution at a lost cost.
Like orifice plates, venturis and nozzles also create slight pressure drops that use differential pressure and square root flow to measure flow rates.
Level Measurement

Differential pressure gauges also measure liquid level. Again, like flow meters, there are many types of level gauges. A simple, relatively inexpensive solution is to use a differential pressure gauge to indicate the level of a liquid within a tank. In open tanks, the high pressure side of a DP gauge is ported to the bottom of a tank while the low pressure side is mated to atmosphere. In this scenario the DP gauge is measuring a column of liquid within the tank, resulting in a reading that reflects the height of the liquid within the tank, often displaying inches or feet of water readings, or percent-full readings.
For pressurized tanks, such as cryogenic tanks, again the DP high pressure side is ported to the bottom of the tank, but the low pressure side is ported to the top of the tank. The result is a measurement of the column of liquid in the tank (the liquid height), often giving a read-out in inches of water or percent-full.

Introduction to the LaserFlow™ Non-contact Velocity Sensor by Teledyne ISCO
The Teledyne ISCO LaserFlow™ is a velocity sensor that remotely measures flow in open channels with non-contact Laser Doppler Velocity technology and non-contact Ultrasonic Level technology.
The sensor uses advanced technology to measure velocity with a laser beam at single or multiple points below the surface of the wastewater stream.
The sensor uses an ultrasonic level sensor to measure the level and determines a sub-surface point to measure velocity. The sensor then focuses its laser beam at this point and measures the frequency shift of the returned light.
The LaserFlow is ideal for a broad range of wastewater monitoring applications. It is compatible with both the Teledyne ISCO Signature Flowmeter and the Teledyne ISCO 2160 LaserFlow Module, depending on the type of installation.
