PMD55 Differential Pressure Transmitter: Flow Setup PMD55 Technical Support · Pressure

Municipal Wastewater Treatment

Municipal Wastewater Treatment · Differential Pressure Measurement — Application Case

Project Overview

The site is the inlet, biological and outlet stages of a municipal plant. The customer wanted Differential Pressure Measurement properly configured on the existing plant, with the aim of differential pressure for flow and filter monitoring.

Technical Challenges

What actually causes trouble is high solids and corrosive fractions, with large diurnal flow swings, and effluent parameters drift and probes foul with sludge and biofilm. All of this means the Differential Pressure Measurement configuration has to involve checking static pressure limit, overload margin and impulse lines.

Configuration

Supply and installation were organised through the pressure range: pressure solution matched to process pressure and temperature. On site this meant checking static pressure limit, overload margin and impulse lines, checked line by line against: stable compliance with Grade 1A discharge limits and online data reporting.

Performance

After commissioning the outcome is filters changed on pressure drop, using cartridges to their full life, and the readings are now used for process tuning.

Food & Beverage

Food & Beverage · Differential Pressure Measurement — Application Case

Site Conditions

This is a Food & Beverage customer whose plant is at dosing, pasteurising, filling and CIP stages. The main task was differential pressure for flow and filter monitoring.

The Problem

The difficulty lies in syrups, dairy and beverages that scale easily, under strict hygienic requirements; at the same time frequent cleaning demands instruments that withstand hot CIP/SIP caustic cycles. Specification therefore means checking static pressure limit, overload margin and impulse lines.

What We Did

We took a pressure range approach — pressure solution matched to process pressure and temperature. Delivery was built around checking static pressure limit, overload margin and impulse lines, with point-by-point checks on: food-safety and hygienic design per 3-A / EHEDG.

Operating Outcome

In service the system performs as intended — filters changed on pressure drop, using cartridges to their full life, with routine maintenance falling noticeably.

Chemical & Pharmaceutical

Chemical & Pharmaceutical · Differential Pressure Measurement — Application Case

Application Context

reactors, metering vessels and finished-product tanks is a typical Chemical & Pharmaceutical duty. The project started from Differential Pressure Measurement, focusing on differential pressure for flow and filter monitoring.

Process Constraints

corrosion plus Ex protection shortens instrument life and makes downtime costly, and highly corrosive media with solvents and crystallisation, partly in explosive atmospheres only amplify it. The Differential Pressure Measurement specification must therefore cover checking static pressure limit, overload margin and impulse lines.

Delivery Approach

Delivery was handled as the pressure range — pressure solution matched to process pressure and temperature. Execution centred on checking static pressure limit, overload margin and impulse lines, together with Ex certification and GMP traceability of records.

Field Results

Operation shows the benefit clearly — filters changed on pressure drop, using cartridges to their full life, with confidence in this measuring point improving markedly.

Power & Energy

Power & Energy · Differential Pressure Measurement — Application Case

Customer Profile

The typical setting in Power & Energy is boiler feedwater, turbine condensate and FGD/DeNOx systems. The measuring point is Differential Pressure Measurement; the focus is differential pressure for flow and filter monitoring.

Key Difficulties

Conditions are high temperature and pressure with both steam and saline water and, on top of that, drift under high temperature and pressure, with very costly unplanned outages, which a standard configuration cannot handle for long. The design therefore starts with checking static pressure limit, overload margin and impulse lines.

Implementation

The scope ran through the pressure range: pressure solution matched to process pressure and temperature. Technically it hinges on checking static pressure limit, overload margin and impulse lines, and on these requirements: compliance with power-industry codes and unit availability targets.

Customer Benefit

In practice this means filters changed on pressure drop, using cartridges to their full life, which cut the workload on the site maintenance team.
