Non-contacting, open channel flow measurement is difficult to get right, especially when there is an ever-increasing need for accurate and reliable flow readings. The DUET is a unique product to Pulsar Measurement and features a patented approach to addressing the issue of accuracy for non-contacting open channel flow measurement. 

Both ultrasonic transducers fire together, continuously monitoring the phase difference of the echoes, and because the distance between the transducer faces is known and constant, the speed of sound is continuously updated in real-time for the process. Meaning the accuracy and stability of open channel flow measurement readings are exceptional. 

The DUET transducer can be combined with the FlowCERT controller. The combined system is MCERTS Class 1 certified, meaning the open channel flow measurement readings from the DUET and FlowCERT meet the industry standard, so utilities across the globe can be confident in their flow measurement.

The Greyline PTFM 1.0 Portable Transit-Time Flow Meter measures pipe flow with a clamp-on, non-contacting, ultrasonic sensor. Measuring the time it takes to transmit one ultrasonic sound from one sensor to the other. The Portable Transit-Time Flow Meter can be used for calibrations, troubleshooting, flow surveys, or as a temporary clamp-on flow meter to replace inline flowmeters. Causing no interruption to the process, no downtime, and no need to cut into a pipe, simply strap the transit-time sensors to the outside of the pipe from 50 mm to 1200 mm (2 in to 48 in) diameter.

The transit-time technology makes the PTFM ideal for clean liquid flow monitoring on applications such as treated water flow, effluent pipe flow, irrigation flow, and compliance with water abstraction licenses.

The PTFM 1.0 Portable Transit-Time Flow Meter can be mounted without interrupting operations and there is no obstruction or pressure drop. With no moving parts, there is little to no maintenance required with the PTFM 1.0, and the unit gives accurate and repeatable pipe flow readings for clean liquids in minutes.

The PTFM 1.0 has now been replaced by the upgraded PTFM 6.1 version which can be viewed here

The PulsarGuard 2001 sand sensor has been specifically designed for the Oil and Gas industry, using acoustic technology to detect sand / solids impact rate. The non-contacting sand-in-oil sensor is connected to the outside of the pipeline with a stainless steel band, meaning there is no need to break into the pipe or interrupt the operation. Using acoustic technology, it detects changes in the signature of flow within the pipe and converts it into a sand / solids impact rate. This makes it the ideal sensor to monitor well productivity and efficiency, detect blockages and/or foreign objects, and monitor the production of sand in oil and gas operations.

The PulsarGuard 2001 sand sensor MUST be used with the iSensys SandAlert monitor or the iSensys SandAlert portable units. The oil sensor is an intrinsically safe unit, ATEX approved to ATEX EEx ia IIC T4, and is made from 316 stainless steel with environmental protection to IP68. Its narrow frequency band makes the sensor highly resistant to interference from background noise, fluid flow, or gas flow.

The PulsarPoint 300 series provides effective management of material storage and flow, empty vessels, clogged or blocked chutes or conveyors, and provides prevention of overflows. The ideal applications for this product are usually found in food and beverage, animal feed, pharmaceutical, chemical, plastics, quarrying, power generation, cement, and other industrial-like industries. They are perfect for those applications that require accurate level measurement of solids.

The PulsarPoint 300 series uses a rotating paddle, the paddle's rotation is interrupted when the material reaches the paddle, causing a clutch to disengage the motor. This in turn actuates a relay allowing an alarm signal to be switched. The product is fully configurable and can be used to signify high, intermediate, or low-level material.

Specifically developed for sand monitoring in the oil and gas industry, the iSensys SandAlert monitor is a sand and particle monitor that is ideal wherever you need to keep wells producing efficiently. Sand production for oil and gas operators is an increasing problem and can cause catastrophic damage to well and rig equipment. The SandAlert provides robust, dependable sand monitoring data, so plant operators can be confident they are operating at the highest capacity possible.

Why Measure Sand in Oil? 

Solids/sand production in oil and gas wells is a growing problem for oil and gas producers. Over the ages, there is a tendency to produce more solids through reservoir degradation. The challenge is not only to avoid solids/sand production but also to optimize well productivity, as even small quantities of solid particles in the well flow can cause significant pipe or valve damage. 

When solids or sand are produced from a reservoir, the production rate is reduced, and maintenance costs go up. It also represents an environmental risk in the disposal of the solids. Produced solids/sand can never be ignored, and any well producing from an unconsolidated reservoir needs to have some sort of sand monitoring system in place, preferably monitoring in real-time. 

The iSensys SandAlert monitor is designed to provide plant operators with the data they need on sand/solid production so that site and asset maintenance and management can become predictive and effective. The SandAlert system can measure sand production directly, without external or additional flow measurement.

When used with the PulsarGuard 2001 sand sensor, the unit can be positioned up to 1,000 m (3,280 ft) away from the application. An optional explosion-proof case is available for the SandAlert that converts the system into one that can be fully installed in a Zone 1 hazardous area. The graphical display shows a general overview of current signal information, a real-time sand impact trace graph, and an overview of relay settings.

Sand monitoring in the oil and gas industry is absolutely paramount to keep wells producing efficiently and at capacity. Excessive solid production in the oil stream can cause catastrophic damage to well and rig equipment. The iSensys SandAlert Portable Sand Monitor has been designed to give oil and gas producers robust and dependable sand monitoring solutions. The Portable Sand Monitor is fitted into a rugged pelican case and is a complete kit including sensor, mounting strap, and 50 m extension lead, ideal for transporting between multiple sites.

When sand is produced from a reservoir, the production rate is reduced and maintenance costs go up, it also presents environmental risks with disposal of the solids. Produced sand enters the processing system and plant operators need to make sure that the process is capable of handling the sand/solids safely. An important aspect of sand management is reviewing erosion rates and removal issues.

The high-frequency, structure-borne acoustic signal generated by a sand impact on the wall of the pipe is detected by the PulsarGuard 2001 Sand Sensor. The acoustic signal is then converted and displayed on a graphic display on the iSensys Sand Alert Portable Sand Monitor.
