Sludge blanket level control is a crucial aspect of any process that includes primary settlement tanks, secondary settlement tanks, and tertiary settlement tanks with either stationary or traveling bridges, clarifiers, gravity thickeners, or sequencing batch reactor systems. Sludge blanket level measurement works by measuring the distance between the sludge blanket surface and the water level. Once the sludge has reached the required density, the accompanying controller will then switch on the pumps and pump the sludge through into digesters, ready for the next treatment stage

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.

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.
