What to Send Us for an Accurate Quotation — The Instrument Enquiry Checklist

Most revised quotations are revised because something on this list was missing. Ten minutes here saves two rounds of email.

Short answer

Process conditions
Medium, working and design pressure, working and maximum temperature.
Connection
Size and standard — NPT, BSP, flanged with class and face.
Material
Which wetted material the process demands.
Area
Safe area, or Zone with gas group and temperature class.
Output
4-20 mA, HART, Modbus, or local indication only.
Commercial
Quantity, delivery need-by date, and Incoterm for export.

Step by step

1
Send the datasheet if you have one

A project datasheet or tag list answers everything on this page at once. We build to it, and where it has a gap we come back with a question rather than an assumption.

2
If you have no datasheet, send a photograph

A clear photo of the instrument you are replacing, with the nameplate readable, tells us the size, connection and often the range and manufacturer. This is the fastest route for a maintenance replacement.

3
State the worst case, not the normal case

The instrument has to survive the maximum, not the average. Give us the design pressure and the maximum temperature — those are the numbers that size the item.

4
Say what the medium actually is

Not "chemical" but the name and concentration. Material selection follows from chemistry, and a wrong material fails in weeks rather than years.

5
Tell us whether the area is classified

This changes price and lead time more than anything else on the list. If it is classified, we need zone, gas group and temperature class.

6
Give the quantity and the date you need it

Stock items ship in days. Built-to-datasheet items are scheduled, and we confirm the date in writing before accepting the order rather than after.

7
For export, add the Incoterm and the port

FOB, CFR or CIF, and the port of discharge. We quote all three on request, and the conformity route for your country is raised at quotation stage, not at shipment.

Quick rules

Fastest route

WhatsApp a photo of the nameplate to +91 98107 02836. For a like-for-like replacement this is usually enough.

Most accurate route

Email the datasheet or tag list to sales@vedikainstruments.com. Bulk enquiries raised as an RFQ get a consolidated offer within 24 hours.

If you are not sure

Send what you have and say so. We would rather ask two questions than quote the wrong instrument.

Frequently asked questions

What is the minimum information you need to quote?

Medium, working and maximum pressure and temperature, connection size and standard, and whether the area is classified. Everything else we can propose.

Can you quote from a photograph?

Often yes, for a like-for-like replacement, if the nameplate is readable. For a new application we need the process conditions as well.

How quickly do you respond to an enquiry?

Within one working day for standard items. Bulk RFQs receive a consolidated offer within 24 hours.

Do you supply against project datasheets?

Yes — most of what we build is exactly that. We size, build, certify and document to the datasheet.

What documents come with the order?

A GST e-invoice with IRN, a test certificate, and on request a traceable calibration certificate and material test certificates for wetted parts.

Still not sure? Talk to an engineer, not a salesman.

Send the datasheet, tag list, or a photograph of the nameplate. Whatever you have is enough to start.
