MSA Dual Zone TriGas Monitoring System
Hydrogen sulfide and methane can build up in a wet well, making for a dangerous and explosive environment for workers and equipment.
The National Fire Protection Code for wastewater (NFPA 820) requires these spaces to be monitored with suitable equipment. Many workers are provided with portable monitors, but this doesn’t eliminate the need for continuous monitoring. Detectors are commonly placed directly in the area to be monitored. A better approach is to continuously extract air from the area and analyze the concentration in the safe environment. Highly visible LED Alarms on the MSA X5000 will alert workers to the hazard before entering the confined space. Additionally, these alarms can be transmitted via the PLC to SCADA, cloud, cell phone, or external signaling beacons.
MSA’s TruCal technology automatically tests the H2S sensor response, which extends the intervals between calibrations and reduces maintenance.
The Adaptive Environmental Compensation technology increases resolution for H2S and unique non-consuming 02 sensor design, extending sensor life from 2 to 5 years for both H2S and O2 sensors.
Longer calibration intervals and sensor life translates into lower operating costs. For CH4, we recommend using infrared absorbance sensor technology which has low maintenance and a 10-year sensor life.
Yokogawa Digital Indicator Controller
The primary function of Yokogawa’s UT55A is to manage the pump control and alarm when levels in the wet-well exceed alarm setpoints. It supports remote setpoint for remote adjustments if required. The UT55A digital controllers employ an easy-to-read, 14-segment large color LCD display, along with navigation keys, thus greatly increasing the monitoring and operating capabilities. A ladder sequence function is included as standard. The short depth of the controller helps save instrument panel space. The UT55A also support open networks such as Ethernet communication.
Other features include: Up to 4 analog inputs, 3 alarm independent common terminals available as standard, ladder sequence programs can be built, simple operation, up to 18 DOs (combinations available) and multiple language operation manual.
HAWK Radar Level Gauge
HAWK’s Senator S24W FMCW 24GHz Radar Level Transmitter is designed specifically to measure liquids in water and wastewater applications. This device is a non-contact radar level transmitter that uses FMCW technology. It measures distance, level, and volume of liquids and pastes. It is a device that provides accurate readings in closed tanks, in the open air like rivers or dams, and can even measure volumetric flow rate.
REOTEMP Submersible Pressure Transmitter
As the level of wastewater increases, the pressure relative to atmospheric pressure increases too.
Many older lift stations use “bubblers” as their primary level measurement. However, these have fallen out of favor as they require a constant flow of compressed air and present yet another mechanical item to maintain.
A better approach is to use a Submersible Pressure Transducer which is suspended on a flexible cable and produces a 4-20mA output proportional to the wastewater level. This technology has proven very reliable and easy to maintain.
As there is risk of CH4 and H2S in lift stations, most are classified as either Class 1 Division 2 or even Division 1.
The sensor is a sealed unit with no moving parts, therefore requires very little maintenance.
FLEXIM Clamp-On Flowmeter
The FLUXUS® ultrasonic clamp-on flowmeter by FLEXIM, offers reliable and accurate non-invasive wastewater flow measurement without any wear and tear or measurement drift. It is extremely easy to set up a measuring point without any impairment of the plant’s normal operation. This is possible for a number of reasons:
- FLEXIM is the only clamp-on flow meter manufacturer that actively temperature compensate their transducers, important to providing long term accuracy and repeatability.
- FLEXIM provides permanent coupling pads to mount transducers. These are life time and never need replacing. (no coupling grease)
- The rugged transducer mounting hardware greatly simplifies installation and ensures transducers do not move over time.
- By measuring the sound velocity, FLUXUS F721 can also calculate temperature of the fluid.
- N.I.S.T. traceable calibration
The FLUXUS includes NRTL certified transducers for use in hazardous areas Class 1 Division 2, and ingress protection degree IP68 in the event of the wet well flooding .
