Meter Calibration for Water Plants and Wastewater Plants

Meter Calibration for Water & Wastewater Plants What is involved in meter calibration of a water plant or wastewater plant? Calibration of water plant meters and wastewater  plant meters is simply: Applying a known standard to the meter Determining the accuracy as found compared to the standard Making the necessary adjustments to bring meter into the manufacturer’s stated accuracy and regulatory compliance Who should calibrate my water meters and plant instruments? Many in the industry prescribe to the methods from the ISA - International Society of Automation. The ISA certifies technicians and engineers to perform detailed instrument calibration and tuning. All of the standards, reagents, thermometers, signal generators and references are required to be calibrated to a standard regularly and traceable to NIST. Lab Trained Technician or Real World, Field Experienced Water and Wastewater Calibration Specialist? Additionally, you should have a field engineer or experienced technician who is not only familiar with meters and controls but also one experienced in water, wastewater treatment processes. In addition to the theory learned in the classroom and technical training, are they experienced with your particular process and not just in lab equipment? If you are in water or wastewater, how long have they been operating in water plants or wastewater plants? Are they also water or wastewater operators who know and understand your process and requirements? Theory in the class or experience gained from other process does not completely translate to the process of water treatment and wastewater treatment. Why should I have my water or wastewater meters calibrated? The simple answer is this. You'll save money and time today in chemical costs and process control. Water and wastewater instrument calibration also typically saves you money in instrument repair and downtime further down the road. For example, a commonly found 5% error in a water meter or wastewater meter found in a 1 MGD treatment process could result in 50,000 gallons per day either being over reported or under reported. If you are paying $ 3.95 per 1,000 gallons pumped and selling for $ 4.95 per 1,000 that is a cost…

Instruments for Refrigeration and Cooling – Nivelco

Nivelco Process Instruments for Refrigeration and Cooling Process Updated October 11, 2014 with video Nivelco and MCE Process can provide all you instrumentation needs for refrigeration, ammonia cooling and related processes.   Get Quote The Nivelco Refrigeration and Cooling process diagram below illustrates a cooling technologic process commonly used in food, chemical and pharmaceutical industrial plants. On the process diagram can be seen the cooling compressor applying ammonia, the circulating pump system and the liquid separator tank with the proposed Nivelco devices. Nivelco Product Used Instrumentation of the compressor: The measurement of the pressure on the suction and pressure side is accomplished by NIPRESS DRC-3xxx type pressure transmitter The measurement of the temperature is completed by THERMOCONT TTJ-Sxxx temperature transmitters The suction side pressure transmitter performs the power control or the compressor, while the pressure side transmitter controls the condenser Instrumentation of the liquid-separator: The continuous level measurement is executed by NIVOCAP CTR-2xxx type capacitive level transmitter This device controls the feeding valve applying me UNICONT PMM-311 type controller The upper and lower failsafe switching is executed by NIVOMAG MKA-210 type level switches, As high level is reached, the compressor shuts off, while at low level the ammonium pump is stopped. Instrumentation of the liquid tank: The instruments and procedure is similar to the separator but a NIVOTRACK MTG or MTC-5xxx type level transmitter is recommended due to the high pressure (16 bar) Instrumentation of the cooling water: A continuous level measurement is accomplished with EchoTREK SGA-3xxx type ultrasonic level transmitter, the level in the tank is kept constant by the help of a UNICONT PMM-311 type controller by actuating a supplementary water valve The continuous conductance measurement is executed with an ANACONT LGK-2xxx type device, The conductivity or cooling water is permanently increasing due to the evaporation in the condenser, so at a predetermined value, the PMM-311 controller opens the emptying as well as the supplementary valve The low and high failsafe NIVOSWITCH RFM-401 type switches protect the pump and issue the alarm signals. Instrumentation of the condenser: The level control of the water tank under the…

Vacuum vs Peristaltic Portable Samplers – ISCO, Campbell Scientific & Hach Sigma
Vacuum versus Peristaltic Portable Samplers for Water, Wastewater, Stormwater and Runoff. ISCO 6712 vs Campbell Scientific vs Hach Sigma SD900. What are the differences between vacuum based samplers and peristaltic samplers? What are the advanteges of vaccum samplers? What are the advanteges of peristaltic samplers?

Vacuum vs Peristaltic Portable Samplers – ISCO, Campbell Scientific & Hach Sigma

We receive a lot of questions about Vacuum vs Peristaltic Portable Samplers for Water, Wastewater, Stormwater and Runoff Monitoring.  We're looking today at three of the leading providers of water samplers and sampling equipment. These water samplers use different sampling technologies and pumps to get the job done: ISCO 6712 vs Campbell Scientific vs Hach Sigma SD900. See the full comparison table of Peristaltic Vs Vacuum Portable Samplers. Portable water samplers use either peristaltic pump or vacuum pump technology to obtain the liquid samples. Both portable sampler pump technologies are designed to quickly move most fluids from the source into the water sampler. Let's take a closer look at Portable Vacuum Samplers vs Portable Peristaltic Samplers So what do you see as the main differences between vacuum based samplers and peristaltic samplers? What advantages are most important for you with vacuum samplers? What are the most important advantages of peristaltic samplers for you? Let us know in the comments below.

48 Hour Meter Delivery and On Site Install
Wright State University and City of Fairborn

48 Hour Meter Delivery and On Site Install

MCE Process is committed to meeting our customer needs and responding on their timeline.  Sometimes this means going the extra mile with a quick delivery and install. And by quick, we mean 24 hour delivery and next day installation.   The Challenge We were contacted by Wright State University at 2:30 on a Thursday afternoon and advised they needed a flow meter on a 12” potable drinking water supply from a public utility. The other important detail that was quickly revealed was the flow meter had to be on line and running by Sunday morning at 7:00 am. Experience and confidence in our solutions and  our team at MCE Process prepared our reply without flinch or hesitation, "We'll be there and have you up and running by Saturday". OK we did gasp just a bit! Our Solution We immediately went on site and assessed the measurement application. Cutting into the line and installing a meter would not fit into the time line for this installation. An insertion paddle wheel style meter simply wouldn't do for the accuracy required or the piping configuration. We decided on a Dwyer Instruments transit time ultrasonic clamp on flow meter for the application. This included the Dwyer UXF2-11P1 Ultrasonic flow converter, SX3-D0 Ultrasonic Flow Sensors and a pair of SX3C-2B Sensor Cables. Meter accuracy was also critical to this 48 hour application. Wright State needed to have a highly accurate meter accepted for billing purposes by the utility. We coordinated with the City of Fairborn and determined a Dwyer meter would meet the application and satisfy the billing requirements. By Saturday afternoon we had the meter installed and accurately measuring flow. A 48 hour meter delivery and installation! We not only sell great products and solutions, we partner with great suppliers, field engineers and team members who understand that normal deliveries do not always fit the in the real world time loop. We always appreciate having adequate time to work and resolve tough installation issues. However, MCE Process is on your side even when time is not. Our onsite field service engineers will travel to your application…
