Question 1

What does Quality Lab Solutions supply?

Accepted Answer

Quality Lab Solutions supplies pressure, flow and level measurement instrumentation for industrial process applications, including transducers, transmitters, flow meters and level measurement for monitoring, control and protection.

Question 2

Do you sell online or by quotation?

Accepted Answer

We work on a quotation basis rather than online checkout. Tell us your application or send an existing part number and we will provide a clear quotation and suitable product options. An engineer reviews every enquiry and responds within one working day.

Question 3

Which industries do you work with?

Accepted Answer

We support OEMs, system integrators, maintenance and engineering teams and industrial buyers across sectors including water and wastewater, food and beverage, chemical and pharmaceutical, power and general manufacturing.

Question 4

Can you help me choose the right product?

Accepted Answer

Yes. We help select suitable products around the application - measuring range, media, output signal, process connection, materials, mounting and operating environment - rather than only matching part numbers.

Question 5

Can you supply a replacement or alternative to an existing product?

Accepted Answer

Yes. Send your existing part number or specification and we will help identify a suitable product or alternative.

Question 6

Do you support OEM, project and repeat supply?

Accepted Answer

Yes. We support one-off requirements, project supply, and repeat or call-off orders. Call-off order commitments enjoy next-day delivery and competitive pricing.

Question 7

What information should I include in an enquiry?

Accepted Answer

For pressure: range, media, process connection, output signal, electrical connection, temperature, accuracy and environment. For level: media, tank height or level range, mounting, connection, output, temperature and pressure, and material compatibility. For flow: media, pipe size, flow range, pressure and temperature, connection type, required output and accuracy.

Question 8

Where are you based?

Accepted Answer

Quality Lab Solutions is based in Manchester, United Kingdom (Colony, 5 Piccadilly Place, M1 3BR). Office hours are Monday to Friday, 8:00 to 17:00.

Question 9

Are you quality certified?

Accepted Answer

Quality Lab Solutions is registered to ISO 9001:2015.

Question 10

What are your lead times and delivery options?

Accepted Answer

Lead times are confirmed with your quotation and vary by instrument and configuration. For repeat and call-off order commitments we offer next-day delivery and competitive pricing.

Question 11

What warranty do your instruments carry?

Accepted Answer

Warranty terms are product-specific and stated on your quotation — typically 12 months for pressure transmitters, transducers and flow meters. If your application needs specific cover, raise it with your enquiry.

Question 12

Do instruments come with calibration certificates?

Accepted Answer

Yes — calibration certificates are available on request. Ask when you enquire and we will include them with your quotation.

Question 13

Do you ship outside the UK?

Accepted Answer

Yes — we ship across the UK and the EU. Delivery options and costs are confirmed with your quotation.

Question 14

What are your payment terms?

Accepted Answer

First orders are typically placed on a proforma basis. Regular customers can arrange 30-day net terms — ask when you enquire.

Question 15

What is the difference between a pressure transducer and a pressure transmitter?

Accepted Answer

Both convert pressure into an electrical signal. A transducer outputs a raw or lightly conditioned signal, typically millivolt or voltage, and relies on the receiving system for processing. A transmitter includes built-in signal conditioning and drives a standardised output such as 4–20 mA, often with digital protocols like HART or Modbus on top. Transmitters suit plant control loops and long cable runs; transducers suit OEM builds and test systems that do their own processing.

Question 16

What is the difference between gauge, absolute and sealed-gauge pressure?

Accepted Answer

Gauge pressure is measured relative to the surrounding atmosphere, absolute pressure is measured relative to a full vacuum, and sealed-gauge is measured against a fixed reference sealed at the factory. Choose gauge for most process and hydraulic duties, absolute where barometric changes would distort the reading, and sealed-gauge for higher ranges where venting to atmosphere is impractical.

Question 17

When should I choose 4–20 mA, voltage or a digital output?

Accepted Answer

4–20 mA is the industrial default: it tolerates electrical noise over long cable runs and its live zero makes fault detection easy. Voltage outputs suit short runs into controllers, data loggers and embedded systems. Digital options, HART over the 4–20 mA loop or Modbus RTU over RS485, add configuration, diagnostics and multi-parameter data for networked plant.

Question 18

What accuracy class do I need?

Accepted Answer

±0.5 % FS is the workhorse class for general monitoring and control. Specify ±0.25 % FS or better for test benches and tight process control, and per-cent-of-reading instruments where accuracy must hold across a wide turndown. Higher accuracy raises cost, so match the class to what the process genuinely needs.

Question 19

How do I size a Coriolis mass flow meter?

Accepted Answer

Size a Coriolis meter to your flow rate rather than your pipe diameter. Each nominal size covers a working band — DN6 to around 1,200 kg/h, DN25 to 12,000 kg/h, DN80 to 180,000 kg/h — and accuracy is best with normal flow in the upper part of the band. Check the pressure drop at maximum flow, and send us your media, flow range and line details for a sizing recommendation.

Question 20

What is a Coriolis mass flow meter?

Accepted Answer

A Coriolis meter measures mass flow directly by sensing the twist a moving fluid induces in vibrating tubes. Because it reads mass rather than volume it is largely unaffected by changes in density, temperature or pressure, and it typically measures density and temperature at the same time.

Question 21

What is an electromagnetic flow meter?

Accepted Answer

An electromagnetic flow meter measures conductive liquids using Faraday's law: liquid moving through a magnetic field generates a voltage proportional to its velocity. With no moving parts and an unobstructed bore, it suits water, slurries and corrosive liquids.

Question 22

What is a differential pressure (DP) transmitter?

Accepted Answer

A DP transmitter measures the difference between two pressures rather than a single pressure. That difference is used to monitor filter condition, measure level in closed vessels and infer flow across an orifice or restriction.

Question 23

What is a float switch?

Accepted Answer

A float switch is a simple point-level device: a buoyant float rises and falls with liquid level and operates a switch contact at a set point, signalling high or low level or starting and stopping pumps.
